Endgame Set I Should Be Aiming For?

I've seen a lot of players running around in the following sets:

AF (I know its a "starter" endgame set)
Relic (bought with tomes)
Darklight (bought with tomes)
Peltast (lv50 dungeon drops)
Hetairos (lv50 dungeon drops)

Which set should I be aiming for? I'm assuming its between Relic and Darklight. I'm currently lv48, should be 50 tonight or tomorrow, and I'd like to have my plans all set out prior :D

Sweet, so Relic is what I'm after then.
I say relic because realistically I probably won't end up in a hardcore raiding company.

Thanks!
