Well I own both so I may as well chime in here.
The LX2 is basically a throw monster in its catagory and pretty good for mid range and further use. The high beam easily throws a pencil thin beam a stinkin' long way (my own unit of measurement
) albeit with below average side spill. The low beam is a pretty good thrower in its own right and great for conserving power for longer duration use. This little guy is perfect when you need to see at range and are not really too concerned with your peripherals. The TIR optic is solid and well constructed and, in my case, the LED is perfectly centered. The beam pattern isnt as clean as with a reflector, but it doesnt make any perceivable impact on practical use.
The A2L-WH is more of my go to light for indoor or mid to close range use. The 10 lumen low flood is great for lighting up a wide area with enough light to preserve your night vision while still getting a pretty good level of detail and a nice long runtime for extended use. The 120 lumen high beam is great for a slight boost to the flood area and puts out a fairly tight, bright, and smooth hot spot with about mid range throw (but not much past that).
They both have their specific uses and I like them both...
