>>8069841The only KO you should avoid is MFT's Cosmos Battles. There are reports of the thigh mushroom connectors being easily broken. Fortunately another KO company, Diamond Cyclone did this version too and it's their one and only release.
For the powersuits, you should be prepared to adjust the fitting of the weapon pegs and holes yourself (sandpaper or 3mm drill bit). They don't maintain the molds as much as the OG, so some sets like the SAT ones are quite worn out.
