Seems as if my emerald thread is going off the topic, but who cares.
I prefer the fire over the ruby lenses, just because the first fire had the same deep red like the rubys (maybe purple is missing.. but I have not seen that much rubys, also gen1, that had purple in it) and they make the world green. But for me emerald goes straight ahead, just because it is so unique (and my pair of juliet ems look sooooo damn nice).
And like Defender I really want to own a carbon/emerald combo, I just need a carbon frame. Someone want to trade? I can throw a titanium and a early plasma (P006896) with fire gen. 1 (but used) and new vr28 bi, usual bi (also new) and used gold i in.
