Like many other people, nothing beats Pally T2 Judgement set.

I always liked the Lightbringer Raiment (holy paladin T6) from an aesthetic standpoint. I think it's the shoulders; they look impressive without being completely ostentatious like so many others have an unfortunate tendency to be.
I would have to say that my favorite set is the T5 priest set, The Avatar Raiment. It's not because of the bonuses or the look of the set, but rather the memories it holds. Back when I was raiding SSC and Tk, I had a buddy named Johnny. Johnny and I both played priests then and rarely could you make a raid with one of us healing without the other coming along. We always were competing with each other but we still made a great team. One day we were scheduled to down Void Reaver and Johnny wasn’t online and wouldn't answer his phone so we had to go without him. We killed Void Reaver and I managed to obtain the shoulder token and I was planning on rubbing it in his face the next time he got on. It wasn’t until the next day that I found out he was killed at a gas station that night when some hoodlums tried to rob the place.To this day I keep that shoulder piece in my bank, so I can keep him in my memories.
Bloodfang, hands down, It just screams (or should I say silently stalks) rogue.
The best set in game is the Tier 3 for warriors... The dreadnaught, it's atleast what i think. I think it's the coolest set because i love the helmet :D It gives this cool blue eyes and the shoulders are so awesome... It's like death knight shoulders and the rest of the armor is nice just cool. First of all this set fits to everyone, second it matched much with hungering cold and the corrupted ashbringer. I just like how its made, its very detailed and awesome looking. I would love to get my hands on this set.
Shaman t10 is my personal favorite, still have it on my shaman with no plans of getting rid of it
My favorite tier set is priest dungeon set 2/Tier 0.5 which I managed to get on my priest before Cataclysm came out and made it obsolete. While plain it still is good looking and I use it everytime I am around in Stormwind.
Druid tier 1: For the epic thorn dmgz
I admit that I'm torn. For my hunter I've always loved the look of the T3 Cryptstalker, but since changing my main to my Death Knight so far it's been T10 with the new T12 coming in second for aesthetic reasons. :)
My personal favourite was the Warlock T0 set, the Dreadmist set. What says Warlock better than a flowing robe of yellow, purple and blue, a hooded cowl with glowing red eyes and skulls on your shoulder pads?
The Warlock's Tier 3 set (Plagueheart Raiment) will always be my favorite. For its time, the stats were great, as well as the set bonuses. Not to mention it looked great too, and it was one of the most legendary things to have. Putting it together may have been called tedious and annoying by some, but I think the fact that you got to piece and craft together your actual tier gear instead of it simply dropping or being purchased was hella fun and something pretty unique to do in this game. If only it were still available. Also, a 9 piece set is awesome. =p
Mage Tier 10 (277 version) on a Gnome was my favorite... I love this tier, especially on a gnome, due to the fact you look like a little king...(explained more below)Jester yells: *All Rise, Hail to the Future King of Gnomeregan and Leader of all Gnomes*King: *Be Seated*King yells: *Where is my THRONE...!*King continues: *Who took my THRONE....!*Jester: * oh-h-h, this is chair is so comfy*
