Baring toon effects, G5 is creative, which is why Luffy vs Kizaru has high potential to be the best fight. I am sure, there will be full-length fight at some point because for Kizaru to finish the mission he has to completely defeat Luffy, stalling won't do and at the same time, to stop Kizaru, Luffy has to defeat Kizaru, throwing away very far or just preventing him won't do.
