I bought these guys because I heard that bootlegs weren't steaming hot shit anymore compared to years ago.
So the bootleg figmas are either hit or miss,
Figma Deku is surprisingly better than expected. The original Figma seemed extremely basic so the bootleg is not much different,
the paint is a little sloppy here and there but unless you have it in front of your face you won't notice.
Figma Snake is a mess, the paint is overall fucking awful, looks like a mod gone wrong, joints weren't awful, super loose but an easy fix.
The foot joint broken in like 3 pieces but I somehow managed to kinda fix it, I already knew how bad it was so I plan on posing him with most of his body inside the cardboard box included.
The Figma soldiers were also super loose and if compared to the real ones the paint probably looks like shit, but as they are they are great grunts to pose alongside all my Snakes.
Figuarts Antman is basically the real deal, just has small paint smudges that are barely noticeable and all joints work well. Same for Iron man except the figure came without feet for some reason (I already got a refund on it)
So based this experience with these bootlegs, I would say go ahead and buy them if you don't care much about the character or if you want to use them as fodder for other figures.
Sometimes you'll get lucky and get a good figure but most of them will probably come with issues.
