ehh still dont like this whole tier thing but basing from the tier 1 in the outdated villager popularity list here:
fave: fang and beau
least fave: rosie and ankha
My least favourite is probably Zucker... I just don't think he's cute enough to be a Tier 1 villager. My favourite would probably be Lolly though and I have her in my town .
I like all of them, especially merengue. She's so frickin adorable and makes me hungry every time I look at her!!! And she's PINK and she likes to cook awwww
