For my 2 cents worth: I own the Palight Gold, Arc-AAA, and EternaLight, all with white LED's. The Arc-AAA is really in a class by itself, due to it's diminutive size. It's a great light, but with only a single LED, it may not put out enough light for many situations. The Palight Gold is quite bright, but is uses a reflector and lens to provide a very tightly focused beam of light. Too tightly focused, for general use, for me at least. And it gets easily turned on in your pocket. The EternaLight is, IMHO, a good compromise. The light is electronically controlled, and with 4 LED's, puts out a great deal of light. Battery life is very, very good. And, the price has been lowered to $39.99, plus shipping, making it a very good value for the money. I have a hand built 3 D cell light that uses the same Luxeon Star light that the Arc-LS does, and it is much brighter than any of the other lights. It puts out a somewhat focused light (compared to a bank of Nichia white LED's) that gives very good illumination. The only shortcoming of the Arc-LS will be that due to it's high light output, and small size, it won't have a very long burn time. This is the tradeoff with a maximum of 2 AA batteries to power the Luxeon Star LED. And, it's considerably more expensive than almost any other LED light on the market (or almost on the market) It's built tough, and as small as possible. If the price and shorter battery life aren't a problem, it's got to be the best LED light available. OTOH, I like the Eternalight, myself. It's quite small, bright, and has good battery life. If the cost and burn time of the Arc-LS puts you off, I'd highly recommend the Eternalight. I'm giving 5 of them as Christmas gifts, plus I bought two for myself. I'm sure I'll like the Arc-LS when I get it, but it's not (quite) perfect. No single flashlight can be 'the best' in every category. The ARC-LS is the LED flashlight that comes the closest, but it's not necessarily the best light for every situation. Like most flashaholics, I have to have all the newest and brightest lights. It leaves me with a significant number of lights I rarely use. The EternaLight is one I use quite a lot, and I expect the ARC-LS will get a lot of use, as well. It remains to be seen wich of these two light I'll use the most. Time will tell.
