darkpeak,
The CPF motto, "buy both" is a little tongue-in-cheek, but it is a reasonable option. If you have a credit card, you can purchase both (don't pay retail) try them out for a week or two in various environments, then sell the one you like least here on B/S/T for almost as much as you paid for it (and will probably have it sold before you have to pay your credit card bill).
But if you insist on purchasing just one, I would normally vote for the A2 (I own three and sold my L2), but you do have several incandescents already. The L2 is a good light if you plan to use it mostly indoors. My beef with it is its limited applications. If you want a multi-stage LED light, that would not be my first choice. I would vote for an HDS U60 (in the same price range) since it is a lot more versitile (throw, takes an F04, programmable, multiple battery options).
