It's very difficult to reply to your question as the bodies have changed over time, and sometimes between release and re-release of a same character.
I disagree with people saying they are garbage. They just reflect the average body that was the cheapest and functional at the time. So yeah, they are subpar, but only if you compare them to today's options.
Now, they tend to use knock off TTs, but of course, a knock off isn't always without issues. To be fair, I own several and have never replaced a body, but then I like my figs in their original condition and I'm not too picky. So unless you're a die hard fan of HT and think that whatever isn't brande HT is pure crap, you should be just fine.
The only thing that was bad, particularly with the earlier releases were the bendy hands, the rest varied from meh to quite good.
