He is a better allrounder but Feliks cubing accomplishments out weight his and all other people. Sure being a allrounder is impressive but Feliks was way ahead of everyone else at 3x3 at his peak (2010-2016ish). He is still one of the fastest. There was a time he was so far ahead of everyone else that most thought he would win 2011 championship hands down. Not to mention his wr count
Also who is a better allrounder Stanley Chaphel or Martin Egdal? Stanley is crazy good at BLD and a good allrounder for the other events.
Being good at 3x3 is harder than all rounding. Everyone does 3x3.
You can think the best all rounder is the best cuber ever but that doesn't mean people will agree.
