How good/bad is the ZC Toys muscular body?

I know it’s a direct copy of HT muscular body, but I never bought ZC Toys before. Is it good or bad? Any loose joints problem? Neck cup cracking?

I have a few. Good solid body, with a nice heavy(ish) weight. Nice Paint finish. Negative: had one with really really tight upper arms - literally need 2 hands to move figures arms!

Overall I have no concerns buying ZC figures. TBH only reason I don’t buy more is I can pick up DAM or E&S figures for less (box split stuff - like what Adam sells)
