>>2310128>>2310140I dunno, I think they each have their pros and cons. To me, the Damashiis just look kinda... clunky, a bit like they were in the original show. The Revoltechs look a lot more fluid and have an almost TTGL-vibe to them, but they look kinda funky when they're not in action poses.
I think the RDs are slightly better figures, but the Revoltechs have much nicer accessories and aren't exclusive. So I see nothing wrong with mixing-and-matching between the two lines to fill out an EVA squad - I have RD 01 and Revoltech 02 doing a back-to-back shooting pose on my shelf right now, in fact.
