I'm with MayorSaki. I really really liked the Lazies in Wild World (my favourite villager was Biskit in my first game) and I love the Uchi villagers in New Leaf. I adore Cherry, I've had her since I started my NL town, and I got Biskit to move in a while ago. They're pretty much my only dreamies.
I'm not a huge fan of the jocks or the grumpy villagers. The Grumpy villagers' voices kind of scare me - all other villager types pretty much have the same voice so why are they different?
