Yes, I have both and I prefer the Tac Tic but the Power Click is more adjustable with a little slider. Mark recommends you train your right hand versus the flat left wrist so it is designed to click and then not unclick.

In reality, for me, they both work the same. The Tac Tic is more comfortable to wear and you don't get stared at on the range wearing it. Both work equally well.
