I had the same question, and I had a hard time finding a good comparison. However, using my h4x0r powers (actually, just google

) I found what I needed before I bought the stuff.

According to them, the ClearFlex can take more bending, but is a little more flexible. Honestly, this stuff seems a lot more flexible than shown in the picture. The only thing is that the ClearFlex doesn't seem to retain its clearness. I really can't see paying another dollar or more per foot.

That's some ClearFlex on my TC-4

. I was actually worried that the ClearFlex would be crappy before I bought it, fearing it would be no better than generic PVC tubing. Alas, my fears were for nothing, it sure is swell tubing.
