Again, my POV is biased based on people I play with... but while I've mainly raided with my raid group, I have been pulled into runs with bigger kins in the past and have pugged more than I'd care to admit outside that. Some of these might be a bit outdated - deal with it. I'm just listing people who stood out in my experience as people who are incredibly knowledgeable of their class.
Best All Around: Shaera - on any class she rolls an alt with. Seriously, it's not fair.
Guard: Agtug, Kraumur, Meatshielder, and He
Warden: Shaera (duh), Jak, Jacbo (back in the day), and Tomriddle (back in the day)
Chanks: Norfrid, Chickendorf (omg that foundry run)
Chimps: Gamarin, Aktis, Delamore, Deyja
Cappies: Bigdennis, Eomen, Erharl, Beornded, Skiddish, Tudhuiros... Anyone who gives me Songbrother, 10% motivation, and doesn't use a pet in a raid...
Hunter: Zulubeast, Vahnya, Katon, Lef, Patriotpea (I love my squishies, excluding Katon, who I adore but only an idiot would describe as squishy.)
Thieves: Frogzie, Thrilos, Olathronn... And the burg pack is well on their way!
LMs: Guido (I'll miss him greatly, even though he's a divisive figure.), Eaisiel, Zaar, Bord (SI isn't everything... and your cc/debuffs are dead reliable)
Mini: Snap, Torqky, Iri, Katrin, and Chocla
Healing RKs: Hmm. Well, I'm biased, obviously. Mimboril (though Mimborill has a ways to go ), Marvi, Stocky, Alohire. And I'd count myself in this list. Because I'm self-important like that.
DPS RKs: Marvi (the lone fire, even if we occasionally argue), Tanar's dps is beast wherever it's used, Augus, RKer, Zepphyr (don't ask him to heal)
I've probably forgotten someone. I'm sorry?
