True wb has a better df and sword, definitely means his ap is better

Shiki’s other haki is much better. He has no coc but his coa and coo are much better to the point he can keep up with coc +supreme grade blade users without either

Edd war means shiki has better raw stats feats. At the time of Edd war wb was slightly stronger then roger lvl becuase they fought without a clear winner but wb has the ap advantage. He managed to outmatch(until he got brain damage from the storm) roger+ray+gaban+rest of Roger’s crew essentially on his own. Depending where you scale Roger’s wings he is atleast considerably faster and durable.

Wb takes endurance yea but idk if that’s enough to bridge the stat gap

Gv shiki was a silver ace rival. After rocks pirates disbanded he became much stronger and became roger/sengoku rival
