I don't think it's neg diff I mean come on there not weak no more luffy with all his gears plus gear 5 would do good plus there the big island size fist,
Zoro has insane ap he would push gerad to keep transforming but if there's no limit then zoro get wreck
Sanji is a good match for pernida since he's fast and can sky walk plus his coo is what's needed to avoid those vains
I'd say they all put up a good fight ateast luffy but zoro and sanji might have a somewhat chance of winning depending on how they handle there battle ,and if there opponents has a limit which we never got but it's nice to speculate
