I've used the HF ratcheting wrenches, Husky (on my boat mainly for the drain plug), Gear Wrench, and Carlyle. Granted I'm not using them everyday, but so far I've liked them all. Of all of these, the Gear Wrenches are my only Flex-Heads and I've used those quite a lot with no issues. I do wish they were 6-point though. But for a flex-head option in a jam they've been great. My go-to ratcheting wrenches are the Carlyle's because they are 6-points. I got them simply because I watched and read quite a few good reviews on them. Mine are not flex-heads but if I remember correctly they are available in the 6-point option as well. As far as HF tools go, I've really never had a problem with their Pittsburg Pro lineup of hand tools. I just make sure to use the right drive sizes so I'm not abusing anything. They do skip sizes though which I find annoying. So that's another reason I went to Carlyle...no size skips!
