Are ko’s any good?

I’ve had about three knockoffs so far, tlk megatron, ss 93 hot rod, and ss 05 Optimus prime. The megatron was a great figure for its price, only the arm was a little loose but nothing too unbearable. However the hotrod wings broke in a matter of days and the Optimus shoulder pin wouldn’t hold so his arm was all floppy, his swords also didn’t stay in place. What I’m trying to get at is that I want a jet fire but don’t want to spend 100 buck for a 5 pack and get 4 figures I already have, I heard the baiwei jet fire was good but I’m too nervous to take the plunge
