Hi Bro~
I have made a couple of TS chains before. The assembly of the chain itself was so much fun and when you get a nice touch for the assembly, it become a very easy job afterall!
I didn't try HD chain before. But as a general impression after doing the 2 chains, the quality of the assembly tool, in terms of hardness and strength against the hammering action, is critical! If the PE backing is easy to be bended, the chain will not be as smooth as it is supposed to be.
I have a couple of shots here is my previous progress:

I think the best is to compare the quality of the PE tooling between the brands. If you have a chance to pick up the real stuffs on hand and check out their respective quality, you will know which one you should go for. In my case, I opt for TS as it was the original idea for the way the assembly works.
Moreover, be aware the MFH also released a workable chane too!
But the assmebly is quiet different from either TS or HD chain sets.
Hope this help!
