I think the Japanese is worse, in regards to females, in my opinion. The women with a more mature voice in Japanese are probably the best. The men win in both languages in my opinion (except Zack).
There´s good and there´s bad of course but i prefer japanese VA, plus i just love hearing Hideyuki Hori scream his heart out when you do an izuna and Lee´s VA is way better now
aye also I have the biggest dilemma with Nyo's voice. In English she sounds good during intros and outros but sounds annoying while fighting but in Japanese it's the opposite xD
