Ben Fogstar is a good bloke and contributes positively to the forum, so it's not so strange that people have a sense of loyalty, it's part of what makes this forum great. He also offers his own wraps and sends free wraps and insulators with orders and offers regular deals and stuff for forum members. ... people like that.
I like my Nitecore because it has a regular power cable and I don't have to mess around with more USB stuff. It's also never let me down over the year I've had it... I don't have any experience with Xtar, so that's the only reason I couldn't recommend.
