For me it's Origins all the way, due to the vehicles, playsets, accessories, and now crossovers. This isn't to say that Masterverse is bad, it's just that it's scale prohibits what I find to be the most fun parts of a toy line.

Fisto was in 4-5 episodes of Filmation. 🙂

I like both but lean more toward origins. The scale, vehicles, playsets, updated articulation, and nostalgia. Even that you can mix and match parts & accessories is cool for making your own customs. Masterverse has more a realistic adult look, but other than that they do the same thing just origins can do more.

For me, it's Origins! Great line to make the vintage scale, but with so much more articulation! Plus I have 10 years of MOTU Classics, so repurchasing 7 - 8 inch scale all over again, is not what I want to do, with the exception of some characters.
