I documented some beamshot comparisons in my Underground Mine thread between a KD C8 XM-L (3A) and my Dongrui All-920 (very very similar to the Jacob A60 and same light as the Uniquefire V3, but XR-E Q5 at 2A). The Dongrui was much better for throwing in order to see detail at long distances. The bright spill from the XM-L just knocks out your night vision to see further. Note I have never compared to a real XM-L thrower type light (and my HD2010 is currently dead to compare to that one).
(This post probably more appropriate in the "A60" thread. )
