I've only seen the ultrafire ones, and the AW ones. I don't think there is much difference since they are both unprotected and have about the same capacity (ultrafire is overstating, 500 mah is not true, more like 350 mah I've heard).
Ultrafire here too. Runtime seems adequate for intermittent use. I haven't had them long but looks like they'll only need to be recharged every 2 or 3 weeks with my occasional use. I'm pleased with the performance.
