I'm actually kinda mixed on whether the xbox or PS3 pad is better. Both have strengths and weaknesses.
I actually play DOA5 on PS3/PS4 pad. Think it is way better in my opinion. Xbox d pad just feels like a block. Weird though, because in DOA4 I had no problem using the 360 pad. I will say though doing inputs like 46 and 16 are easier on Xbox.
