Sorry to butt in, bud, but it's hard to compare the two. Eva's had 15 years and a million different spin-offs and re-imaginings to justify (mostly) the massive quantities of merch; 00, on the other hand, first aired... two years ago? Or was it a year-and-a-half? I'm not sure, personally. But, if you meant to compare the Gundam franchise as a WHOLE to Eva, then... it has oodles more merch. There have been about 857 quadrillion Gundam series', after all, and even the "bitch" ones (Turn-A Gundam, for example) have been milked for all they're worth. ):
