I spent my money on B and here's why:
When I was buying, the proprietor of the store took me into his back room, turned out the lights, and showed the different beam patterns. The room was about 25 feet deep. The hot spot of A was slightly brighter than B. However, A had no "spillage," or illuminatin outside the hot spot. None at all, you just got a hot spot in an otherwise dark room. B's hot spot was nearly as bright, and there was sufficiant spillage to illuminate the entire room.
The "throw" is slightly longer with A, but throw is generally not the strong point of LEDs anyway. In my mind, the B gives a much more usable beam pattern.
If you are really planning on using it primarily outside, you don't want a LED, you want an incandescent, for the longer throw. Unfortunately, there is no incan x200, and all of the other SF options tend to be more problematic for holsters and such.
As always, this information is worth exactly what you paid for it.
