I've had them both and loved them. The beams are pretty much identical. The OP has a cree halo too but it really does not make any difference at all, they really were virtually identical.
At least my 2 were the same beamwise but the tint was slightly different and this was more significant.
If I could go back in time I would get the R100 version, many on this forum seem to prefer it although reliability issues put me off it at the time of purchase.
You can't go wrong with either and they are great flashlights!
If you are even slightly technically minded a Romisen RC-G2 mod would be better for throw as the reflector of the L2D can not be tampered with or changed easily.
Have fun!
