In terms of fighters, competition, and overall preference. My list:
1- bantam weight: one of the 2 most dangerous divisions, with lots of entertaining fighters
2- lightweight: I think it’s just as competitive as bantam weight, I think bw is just more entertaining with their speed
3- feather weight: super interesting right now with a lot of new rising contenders
4- middle weight: was lacking for a while but is now in a good place of good competition
5- light heavy weight: lots of heavy hitters could switch with fly weight tbh
6- fly weight: lots of new fun rising contenders
7- heavy weight: jones holding it up tbh, and too many slow fights
