We have the Feedback Sports stands at the shop where I volunteer. Once you get the bike mounted in the stand, they're fine, but I'm not fond of the clamping mechanism -- it takes too long to work. With light weight bikes I'm sure it's not so much of an issue, but with the 50# behemoths we see in the shop it can take two people to get a bike in the stand: one to support the bike and another to tighten the clamp.

I bought a Park PRS-3 stand for my home shop over 30 years ago and have never regretted it. One hand can quickly clamp the frame without the tedious screwing the Feedback stand needs. The Park has taken everything I've thrown at it, even our tandem, without problems.
