A2 definitely. I'd say it's the toughest out of the 3 and most battle ready, I've heard stories about the FAMAS' furniture cracking
L85A2. Tried an Ares TAR-21 and hated the feel of it. Don't like the look of the FAMAS. Favourite bullpup is the AUG A1 or A2.
Real steel I don't really know enough about the TAR or the FAMAS, but their weight alone will be a major plus over the L85. In airsoft the L85 wins hands down just because there isn't a good FAMAS or TAR lol.
