4sevens, the company that initially brought Fenix stateside (as their distributor) and then ate their lunch (with their new Quark lineup) makes excellent, excellent lights. They are (IMHO, and I'm biased because the owner is my friend) a good deal better than Fenix and I recommend them often, as they are solid, bright, and relatively inexpensive. I even carry one myself (right now, a Preon II) as part of my EDC. They are the Spyderco of the lights world -- small, fast-moving, innovative, and offer the latest and greatest in LED technology at affordable prices.
However, Surefire really knows how to make a light. The lights just ooze quality, much like a Sebenza. They look good. They feel good. They work good. Not only that, they are pretty much the industry standard. You can take a 20 year old Surefire and upgrade it with parts from Surefire directly, or from others who build stuff based on, and for Surefires. I have now a Surefire C2 that puts out 300 lumens out the front and runs for 2 hours. It makes the path in front of me look like daylight. I have an E1E that puts out 230 lumens from the front and runs for half an hour. I can light up the side of a 30 story building with it. I can get a bulb for my E2E and some special rechargeables that makes it 500 lumens... for 10 minutes. A real scorcher. None of these come cheap, but there's something nice about having something nice enough to be worth upgrading, instead of dropping it for the latest model.
