Bumping this because I want some opinions...

Now that we have the apparently-very-good Titans Return Wolfwire, how do they stack up against each other?
There's a cheapish pre-owned UUUU in one of the hobby shops in Osaka, and I'm wondering whether to pick it it before I head back to Oz or just grab a TR Wolfwire (who I rather like the look of) sometime instead.
I like Wolfwire's wolf mode better (plus he has, you know, an actual gun), but the headmaster and claws-for-hands design on UUUU looks pretty cool. I don't have any FansProject Headmasters yet so I don't really know about the quality of the line in general.
Is UUUU worth the ~2x price tag?
