Thus far, this jives with my experience of things as well. Fighters are beastly, Rangers can kick all kinds of butt (ours dropped 78 damage from two crits at the start of a fight yesterday--admittedly, in part because of Stalker Shaman bonuses, but still), and Warlords get *all* the love when discussing leaders whether mathematically or thematically. Ironically, Wizard took a while to earn the distinction of "best controller." In fact, I'd almost say Wizards were the class that grew the most over 4e's run...if it weren't for the big, big goodies Paladins got in Divine Power (and, more arguably, the incremental improvement to Warlocks over time).
