I mean.... I think there's a difference between 'I like these' and 'these are objectively better than those.' Marvel Legends are almost always good quality figures, they've pretty much nailed down how to handle all their articulation choices, etc etc. The figures of Spider-Man they did largely suffered from inaccuracies. Unfortunate, for sure. But like... Ellie's articulation looks like absolute shit, and Kratos is the same size as Jin. The Spinmaster line is a bit of a fuckin' mess itself. And I say that as someone that -also- likes all the figures I have (Jin, Kratos, and the TLOU set) a fair bit.
I think, if this line had SM figures in it, they'd be kind of mediocre. At the very BEST, they'd be just as bad as the Legends ones, but in a different way (weirder-looking articulation, weird scaling, probably a lot less or less-useful articulation.. etc).
