A few thoughts:
-I think the list is interesting as a kind of snapshot of "what does Marvel want to push now".
-Like others have said, intelligence is tough to rank and it would probably make more sense to do tiers instead of a straight ranking.
-To be viewed as legitimate I think a character needs a bit more history. Some of these characters have been around for over 50 years with their genius as an integral part of their character, so when you have Moon Girl and RiRi Williams who I think were both introduced in 2016 outranking traditional geniuses, it creates some pushback. A few years ago you would have seen Blue Marvel on this list, and now he isn't included. I've read comics for decades and never read a story with either of them as a character.
-I like the push to have females and non-Caucasians represented, just think it could have been done in a more organic way.
