Ugh, I hated the Yhar'gul set. 
On the other hand, a certain vileblood armor kicked ass.
I haven't really given much thought to this, but there's some candidates:
Raiden's Skullsuit:

Simple design, but elegant enough to be alluring, and comfortable to tackle down any terrorist organization.
Sam Gideon's DARPA Suit:

This suit might not be the fanciest thing in the world, but given the incredible offensive/defensive capabilities, the maneuvers and the overall white/green design, this one ranks very, very high. As armor goes, this thing is top tier.
White Hawk Armor set, from Dragon's Dogma:

Just look that magnificent attire. It probably belongs to some majestic swordman.
I'll probably remember more later.
