Sure but the history will only record trophies and rm fans will always brag with "their" triple CL in a row performance and thus forever say they were the best team/club in recent history too which is as false as hell since Barca 2009-2011 was way better than any rm side I've ever seen including 2016-2018 team.
In the end football is all about personal sensation. Those Barca v Madrid teams are a bit like Messi v Ronaldo.
In some areas it could be argued Madrid/Ronaldo were better, but the majority of fans, players, coaches, experts know that Barca side was one of the greatest in history and same goes for Messi.
Tbh I've never heard people say 3-CL-Madrid was better than Pep's Barca.
