I don't have direct experience with the HF winches specifically, but I have messed with other Chinese winches. They all seem about the same to me...which is, they are reasonable and they work, but don't expect them to be really nice. I had a Champion 8000 on my old 4runner that saw a fair amount of use, and it always worked like a champ. It always sounded like a box of rocks when in use though.
I currently have a Bulldog 9500 under my 80. I haven't done much more than play with it, but it also works. It's quieter than my Champion, smooth but very slow.
For occasional/incidental use, I'm OK with cheap winches. (whether HF or any other...all are equal to me, so just get what's cheapest) If you want something you can really rely on, buck up and get a Warn. You can buy 3 or 4 HF winches for the cost of one Warn though, so it really depends on if you have a real NEED for a winch or just a desire.
