Cristiano NT career is possibly better than R9. He's the Euro top scorer and 1 off from being the top assister as well, He scored 122 goals, All in competitive matches. His peak performance are as good as any all time great player in the national shirt, Spain 2018, Holland 2012, Sweden 2013 with couple of good/great performance against Germany 2020, Hungary 2016, Czech Republic 2008 (Which was rated 7th in the world before the EURO according ELO, Portugal was 19th btw) and many more in the qualifications (Which always been a problem for a small NT like Portugal).
And something very crucial that nobody seem to mention when this discussion arise, And it's Portugal being a non-contender in every single tournament they played (Except 2022 Worldcap with "past it" Cristiano), In fact, Portugal only qualified for 3 WC's and EURO between 1930-2006, 76 years before Ronaldo debut, Out of possible 36 tournaments, With him they never failed to qualify even once to either. He never had a chance to begin with yet managed to achieve *WAY* above the expectations (Which recently revisionists try to claim Portugal was always elite national team by riding their current impressive squad and success in the past 20 years, Failing to mention that Portugal success is directly a result of Cristiano presence, Ironic).
Also, I don't think R9 ever had the liability of needing to step up and "carry" his team, With Portugal it was "Ronaldo pull a great performance or we lose", At least up until recent years.
At club level it's a non-discussion, Cristiano basically provided better peak seasons, consistency and big game performances than R9 by 2012, And i feel like i'm being generous to R9 here tbh.
