Well, with the caveat that I haven't needed them since I took up Chi Running, ditched the orthotics and started working on my hip strength and foot and ankle strength and mobility ...

I did use them for several years. I tried them all and IME the Futuro brand is the most comfortable.

If you have kneecap tracking problems (which is what they usually mean when they say "runner's knee"), a sleeve like the second one you linked to can actually aggravate that. Plus, my experience with those is that they chafe the popliteal area something awful.
