I own Legendary Godzilla figures from SHMA, HIYA and NECA, and of the three, I crown HIYA the winner.

I will say, compared to Legendary Godzilla, SHMA's Minus One Godzilla is a much better figure and looks and feels at the level of HIYA/NECA, but their paint work still pales to both. It would be great to see HIYA tackle Minus One.
In my opinion, if HIYA and SHMA both make a given figure, I'd go HIYA every time, I'd only go with SHMA for lack of option. SHMA's added articulation isn't worth the extra money, and achieving it means aesthetic choices that hurt the overall look of the figure.
