You honestly think Rudy is "significantly better" than Paul George? I don't think he is even better, let alone significantly better.
I do, and I think it is pretty clear if you look into the data. Gobert's impact metrics are generally better, his basic stats are arguably better, and up until the last season when George teamed up with Kawhi Leonard Gobert's teams won more often. Gobert and the Jazz also handily won the head to head playoff matchup with George and OKC in 2017-18. I'm going to go back to 2016-17 for all the stat comparisons because I think that was the first year Gobert was the best player on the Jazz, and George was well established at that point.
Gobert was better than George in PIPM, RPM, and RAPTOR 3 of the last 4 years (2 seasons ago when George was 3rd in MVP voting is the exception). Gobert also had a better BPM in 2016-17 and 2017-18, although George had the better BPM in 2018-19 and 2019-20.
The basic stats are about what you would expect, George scores and assists more (the assists difference is not as big as you might expect though, George hovers around 4 per game to Gobert's 1.5) while Gobert rebounds more. George gets more steals and Gobert gets more blocks, but aggregating them together gives Gobert the lead. And while George is obviously a better 3 point and free throw shooter than Gobert, Gobert's dunk efficiency means he clobbers George in TS%.
My data visualization in this post is pretty crude, but hopefully it's not too hard to read. I highlighted whoever's number was higher in green on each of the stats, although for turnovers and fouls higher is worse so the highlighting is a little misleading for those.
