Wrath of the Lich King - Best of each class

I'm wondering who people believe is the best of their class. On wrath of the lich king, across all realms.

i didn't played all, but for the ones that i had tried:

rogue, good defensives, instant cc and damage combination. a druid can stunlock too for example, but rogue can get good damage while the stunlock happens and cc a second target.

hunter, very complete class. Good for solo, the pet mechanic allow more options in how to face enemies. for example vs elites you have 2 hp pools, between growl, feign death and distract shot you have the tools for pin pon a hard mob.

druid, if you know how to use the specs is very versatile, bear is the less hybrid of the 3, because if you shift out you will die, but feral and balance for example can throw a few heals when needed, roots, tranquility, rebirth and innervate.

very subjetive, but feral is engaging to play.
