I've seen some stupid debates at spoiler room like admirals without their df and kaido without his df is shit
Zoro without swords, sanji without his legs are also shit
Just accept their power as a whole. Mastering a devil fruit , swordskill or brute strength are just ways to become strong. Having some skilled swords or haxed OP DF's ,a character cant outclass another one with these. Choosing the right route which you can use your capability at its max is the road to become stronger.
