I think peppy is my favorite, I just loooove Pate (also reeled for like three days when I found out she was a girl). I like cranky too but I feel like their dialogue gets repetitive really quickly, maybe because I have two crankie's in my town.
This is hard, but I'll go with snooty! Lazy is a really close second, though. I picked snooty over lazy because I tend to get my favourite snooty villagers long before my favourite lazy villagers in all of my towns, so I often develop a really deep bond with the snooty and they're like my best friend for ages.
Uchi without a doubt! I love talking to Uchi villagers! They're always so caring and thoughtful, but not in a creepy way. Their writing was really well done and they have some really funny lines.
My favourite personality type is peppy. My favourite villager is a peppy and I love that they're so full of energy at all times of the day. They're also really humorous to listen to whenever they go on a rant or they're in a conversation with another villager. They're a bit toned down in new leaf and not as hyper but I still consider them one of my favourites. Can also relate to how often they talk about craving a certain food.
