No and it's a huge discussion in Brazil with plenty of people prefering Romário. The fact that you think it's a wind up says it all about how much people are elevating Ronaldo Fenomeno here.
To be honest I don't really know anyone who would put Romario above Ronaldo. He's a great forward but he doesn't stack up to him. I'd like to see some other reasoning but can't really see an area he'd beat him, especially going through their peaks.
Despite the Serie A having great defensive lines out of the 15 years of Cristiano's career only in 2 years there was a goals per game average in his league superior to Serie A in 1997/98 and 1998/99. 4 years only for Messi too. So how good defensively was it really? It was tougher for him to score because the league was more competitive, not because the games had less goals and defenses were that good. Despite all the praise of Fenomeno's time at Inter he essentially just played 2 actual seasons of football there.
Goals per game doesn't tell the whole story. At all.
During the 90's Seria A was crazy good and stacked with excellent teams.
Take the European cup finals during the 90's:
CL:
90' Milan - W
92' Sampdoria F
93' Milan - F
94' Milan - W
95' Milan - F
96' Juve - W
97' Juve - F
98' Juve - F
UEFA:
90' Juve - W , Fio - F
91' Inter - W , Roma - F
92' Torino - F
93' Juve - W
94' Inter - W
95' Parma - W , Juve - F
97' Inter - F
98' Inter - W, Lazio - F
99' Parma - W
CWC:
90' Sampdoria - W
93' Parma - W
94' Parma - F
99' Lazio - W
To recap - only 1 year in CL at that time had no Italian teams in the finals. Same for UEFA and 6 in CWC.
At the time 13 CL/UEFA/CWC were won by multiple Italian teams along with another 12 finalists.
So no, it's not the same as having Real and Barca and occasional challenge from Atletico, Valencia or Villareal. All those sides had teams that could go all the way and dominated Europe through the 90's.
The defensive lines I think it's unquestionably better if you go past statistics and the actual teams/games. Their performance in Europe back that up as well.
Combine that with Inter having a dysfunctional team and no players of the same caliber alongside him.
The Barca team he peaked for was also on the wane (Cruyff's dream team) and was a process of rebuilding.
Some quotes from that time:
“That season Ronaldo was unstoppable. He just blew you away. He scored 47 in 49 games. You watched him and wondered how he had done it; you knew you’d never seen anything like it. Barcelona won the Copa del Rey, the Cup Winners Cup and the Spanish SuperCup. It scored more than 100 league goals — Ronaldo got 34 of them. When Barcelona effectively lost the league, it did so in Alicante against Hércules. Ronaldo was back in Brazil. “That day our beast was missing,” said Pep Guardiola, saying it all. Watch the goals again and it is incredible just how often he went around the keeper — something that adds a kind of childish pleasure, a sense of sheer superiority, to his goals. People talk about walking the ball in; Ronaldo so often did. All it lacked was his getting on his hands and knees and heading the ball in from the goal line. He was slim and powerful, skillful, fast and deadly. He was ridiculously good.”
— Sid Lowe (Sports Illustrated, 2011)
That's true for La Liga but what about this?
Cristiano had it pretty hard in the Premier League too. He came back after the World Cup in 2006 to get kicked and booed more than ever, he thrived and led United to the title. Messi and the whole Barça team has had teams trying to stop them winning by kicking them too.
That's not peak Cristiano tho, and certainly didn't put the same numbers at United compared to Ronaldo at Barca playing for a better team. Messi had people kicking him, but he also had Xavi, Iniesta, Eto'o, Ronaldinho, etc - players who can divert attention. Playing against Inter or Barca at the time had one single plan - stop Ronaldo and you'll take something from the game.
He doesn't have the finishing, crossing, aerial ability and off the ball movement of Cristiano, the finishing, passing and vision of Messi or the set piece ability of either. But most importantly he doesn't have the consistency at the top of most other greats. Cristiano has been in the top 23 of the Ballon D'Or for 13 straight years now, soon to be 14 and it won't take long before he has more appearances than the likes of Giggs or Maldini. Messi is 2 years younger but if he doesn't get injuries he'll get there too, that's how long they've been around how many matches they've played. If you only take their peaks into account then Ronaldo Fenomeno is probably better than anyone else, but for their whole careers there's no question.
We're talking about peak here tho, not consistency. Of course when it comes to consistency both Messi and Cristiano blow everyone else (bar Pele) away.
If the question is 'For 3 years would you rather have Ronaldo or Romário at your club?' the answer is Ronaldo but if the question is 'For 10 years would you rather have Ronaldo or Romário at your club?' then it's easily Romário.
If I have to chose just three years who would' lead the line for 3 years peak? 96-98 Ronaldo is certainly better in terms of peak level to Cristiano. Right up there with Messi and up for debate on who would you take.
As for how highly he's rated, here are some quotes from some of the best managers in the game:
“Ronaldo, the phenomenon, was the greatest player I have ever coached.”
— Fabio Capello
“If we are talking about singular players, Ronaldo is one of the most singular ones. He can get no ball for the whole match and determine the match with one action of his.”
— Vicente del Bosque
“Ronaldo was marvellous. He had one year with me at Barcelona, I bought him from PSV, and he was out of this world. He was a god, absolutely fantastic. He had amazing ability, was a great young athlete, a nice character, respected me and it was sad he only played eight months for us there. [ . . . ] The year he had with us you could see he was going to be phenomenal. He was so strong, would go past people, come deep to get the ball, turn and whatever you put in front of him there was a chance he could always go through you. Power and skill.”
— Sir Bobby Robson (when asked about the best signing he’d ever made)
“I once saw Ronaldo score a goal for Barcelona where he beat five or six players. As I’ve said, he was phenomenal. [ . . . ] Maradona at his best was the best I ever saw. A superb player. Ronaldo would be a close second though.”
— Sir Bobby Robson
“Coaches recommended a second defensive line against him because everyone had the impression that Ronaldo would be able to lose his marker, whether it was with a sprint, or facing a defender directly.”
— Marcello Lippi
“After Maradona the best player was Ronaldo [ . . . ] it is my opinion that he is the best of the last 20 years.”
— Jose Mourinho, after Klose broke Ronaldo’s record for goals scored in World Cup finals in 2015
Romario was great of course, but he was never rated like that. Ever.
