I like having at least 1 of each personality though I also think none of the uchis are that cute. Right now I have 1 smug, 2 normals, 2 lazies, 1 jock, 1 snooty, 1 peppy, 1 cranky, 1 uchi.
Planning on replacing Apple, marina and flurry with sylvana, Marty and ketchup so then I'll have 3 lazies and 1 normal instead
I try to keep a nice balance of villagers. Often when I have only one villager of a personality type, I usually try to keep them from moving.
Which sucks because I let my last uchi villager leave before I decided to do that (Paula). Those are rare villagers in of itself, and I only have one uchi card that... I don't really want in my town. (Muffy)
Right now I have two snooties and one of everything else (but a second uchi is moving in tomorrow. ^_^)
I try to keep a good balance but generally I prefer female villagers/lazies. I'm especially not a huge fan of smug villagers... I don't find most of their designs appealing and personality wise they're my least favorite. When I start my second town I'm not planning on having any smugs in it.
I have... 2 Jocks (Rudy, Curly), 2 Normals (Merengue, Lolly), 1 Peppy (Carmen), 1 Uchi (Shari), 1 Cranky (Bruce), 1 Lazy (Stitches), 1 Snooty (Diana)~ I currently only have 9 villagers as I did let go my only Smug (Marshal)
