I have both and can only echo what was said before: Perfect V4 is more adjustable - since I got it I have made all my V4 chracters with it, and now the updated "complete" system is out (easier to work with, one button to apply) I am even happier - the only sort-of problem is that it means I have not really tried i13's offering to compare it!

What i13 DOES have that XandM doesn't is a version for M4 as well. That is gold. Thanks to i13 for that !

I'll be watching this thread.
