Well as for attacks, since this is all this chapter was about guess I'll give my two cents.
Brook: Thought his was really cool in the whole freezing and ice stuff going on and good one liner there. Might have been my favorite, even though it essentially looked just like his old attack but having ice involved
Usopp: Hated his big time. Just random different plants coming out and doing shit. Seriously feels like he could have done this 2 years ago or even back on his home village as long as he had the pop greens. I loved how he used to make his weapons and combine shit together, here just shot a pop green that did all the work for him. Feels like he didn't improve in the two years, just found better ammo.
Chopper: Looked really weird in that form being shy, but otherwise for his finisher, just felt like his normal monster self, just in control, nothing wrong with that, just nothing exciting
Franky: Pretty awesome to be shooting beams, not much to say really, he is up there with Brook in this chapters winners.
Jimbei: Did he pop a hole through him, or just hurt him enough that he let air out his mouth? Either way pretty insane water technique to go through that whole body.
Sanji: Some more neat flying, not sure if him being totally on fire is part of the attack or a gag at moment, but otherwise cool attack, though i'm getting tired of hearing about Sanji's island trama. Kind of like his nose bleeds with woman earlier, enough is enough we get it, your island sucked.
Zoro: Besides his lines, his was like choppers. Really just felt like watching Zoro do a normal onigiri that he has done since day 1 to one shot a main enemy. While that in itself is saying something that he just did basically an onigiri to beat a top guy as for spreads it was kind of boring. was expecting his asura or something since sanji is been doign his diablo jimbe so much
If I were to rate this arcs fighting I would say my top 5 favorite moments were. (#'s do not mean anyting, just listing)
1. Zoro's tornado whirlwind attack
2. Brook's illusion attack
3. Nami's lighting cloud whip
4. Robin's double clutch
5. Usopp's exploding grass
