Yes, Ronaldo is a better player than any on that list.
My point is not to overlook the 115 goals, as least half of those goals were against semi-proffesional/rubbish teams.
For comparison, i don't believe Lewandowski or Lukaku are better than Henry for scoring more goals against dross/semi-pro teams in UEFA qualifiers.In the same way i don't think Cristiano have better performances than Messi in International football just for scoring more goals against semi-pro teams.
I am not suggesting people to compare Ronaldo and Messi international goals stats directly, as they are from different region so there could be inconsistency to compare them, in the spirit of "apple to apple" comparison. But I always firmly believe if we compare with them other top players under similar settings/criteria, we may be able to judge by how dominance they are over those players in a more comparable sense, and this may give us better clues on how good they actually are (in terms of scoring international goals).
Let's not go into too much detail on many goals Ronaldo score against lesser teams or cannon folders, its simply not fair and will fall into case of double standard easily, as you only do it under microscope on Ronaldo, but not on anyone else.
And if we limited the scope on comparing those players who are actually overlapping with Ronaldo in majority of their playing career (lets say during 03-21 for Ronaldo case), and scale it to max 100%, with only players strictly playing under same region/competitions in same era:
Ronaldo - 115 goals during 03-21 (100%)
Lewandowski - 72 goals during 08-21 (62%)
Klose - 71 goals during 01-14 (61%)
Lukaku - 68 goals during 10-21 (59%)
Ibrahiminov - 62 during 01-21 (54%)
Dzeko - 60 goals during 07-21 (52%)
David Villa - 59 goals during 05-17 (51%)
Rooney - 53 goals during 03-18 (46%)
You can see all other top players who are comparable are only around 46% to 62% as good as Ronaldo, which actually shows how dominance Ronaldo is over the other top players.
In the same way, we could do the same on Messi if we want a fair comparison, and comparing him to other South American players who are overlapping with Messi in majority of their playing career (05-21), to see how dominance he is over others under similar criteria/condition.
Messi - 80 goals during 05-21 (100%)
Neymar - 69 goals during 10-21 (86%)
Suarez - 64 goals during 07-21 (80%)
Cavani - 52 goals during 08-21(65%)
Sanchez - 46 goals during 06-21 (57%)
Falcao - 35 goals during 07-21 (43%)
Other top players who are comparable are around 43%-86% as good as Messi in terms of scoring in international games under same region and similar settings.
Of course, there could be arguments on how good the players from different region are when comparing, so we will probably never come to same conclusion. But at the very least, this may give us better clues/picture on international goals comparison across different continent, at least in a fairer sense.
