My top 5 would be
Urban Rager (barbarian) I Like the ability to pick the boost that is the most appropriate for the situation. In addition it gave a good flavor for a non tribal barb.
Vivisectionist (Alchemist)I like rogues it is by far my favorite class so any class that can get sneak attack and be roguey is a plus in my book. Sadly the flavor was difficult and very dark to play.
Now for my favorite class:
In my mind rogues in literature tend to fall into three type; Magic, Assassin, and Thug these 3 archetypes represent my favorite ways to play a rogue.
Eldritch Scoundrel (Rogue) I have always loved reading of the trickster rogue or the little bit of magic rogue plus lots of wits rogue. This allows me to play that class.
Knifemaster (Rogue) Assassins need one tool to do their job...a dagger and no archetype uses the dagger better then the knifemaster.
Thug (Rogue) Everybad guy needs an enforcer. Appropriately enough the Thug makes for real good well...thugs.
