>>8368227The Play Arts Kai ones are overpriced and kinda bad looking in the face for the most part, I would avoid if I were you.
Figma Snake (MGS2 Ver) is...not great unfortunately. They really fucked up his face. Figma also made a Gurlokovich soldier though, who is quite good.
You will probably have the most fun with the Revoltechs. They have covered Peace Walker, Rising, V, and in the Mini scale (4" tall), the original MGS and V. They're some of the most insanely poseable figures ever, you just need to get used to how Revolver joints work if you're new to them.
