I have a couple of these and would easily rate it either first or second. As far as strength and durability go, the increased wall thickness of the aluminum bottle used on the white box stove easily puts it at the top of the list.

I also really like the fact that the white box stove is designed to be strong enough to be used without a separate pot stand, and Bill is perhaps one of the most stand-up guys you'll ever find on ebay.

The only other alcohol stove out their that even comes close to Bill's IMO is the Anti Gravity Gear Caldera Cone 10-12 alcohol stove. The design of this stove (12 air inlets in the OD and 10 air outlets in the ID, with a center flame) contribute to making it the most efficient stove I've ever used. For a given amount of fuel, the 10-12 stove will easily run almost twice as long as anything else I've used.

To be fair, I haven't run a side-by-side water boiling test (so even though it runs twice as long, it may actuially take twice as long to reach a boil as far as I know) but my impression is the 10-12 will do more cooking on less fuel. I also really like the center flame design, allowing me to use a smaller container without risk of the flame overshooting the cup.
