I'm planning on getting this game soon and I definitely plan on getting some of the DLC characters. However, I do not know how big my budget will be, so I'll likely get two or three at most. Kshatriya is the must-buy, but I'm not sure on what 00 Gundams to get. Arios looks pretty good, Seravee looks fun, Cherudim seems alright... probably not going for Mr. Bushido, though (doesn't look nearly as good/interesting as the rest; even if I get "all of them", I'll probably skip him).
So yeah, if I can only get one of two of Arios, Seravee, and Cherudim, which would you recommend?
