I have two Normal and two Snooty as of right now which works well for me. I've had two Peppy and it was okay. Didn't like having two Smug at all. I haven't had two villagers of the same personality types other than the ones I listed.
I'd be ok with multiple of any of them except lazy and sisterly. Lazies talking about bugs creeps me out, and the sisterly villagers seem unusually rude and out-of-character.
As for which personalities I actually do have multiples of, I currently have two normals, two peppies, and two lazies. (I got Sherb at the campsite when I already had Zucker and Cranston, so now I'm trying to keep Sherb and keep the other two to move out.) By the time I get all my dreamies, I plan on having two normals, two peppies, and one of every other type.
Currently have 3 normals lol. I guess im ok with it since they're so sweet. im ok w/ sisterly and jock duplicates.
i'm probably never going to get another lazy, cranky, snooty or smug, because i dearly love the ones i have now and it'd ruin it for me to have a copy of them. Especially Curlos. ;c
I'm fine with two smugs at the moment, as they're Marshal and Raymond. That being said, if Kid Katt ever shows up at my campsite, I'm probably going to kick out Raymond.
My two snootys are Whitney and Diana. I love Whitney, and I... like Diana. So, if an interesting female villager shows up at my campsite, I'll probably get rid of Diana. Don't hate her or anything, but she's only just okay to me.
Almost all the personalities, except for jocks. I don't have a lot of favorite jock villagers except for maybe two or three. If I really had to choose, I always make sure I have an even amount of genders on my island, so the last two villagers will always be a male and a female. As for personalities to choose, lazy and peppy definitely.
I am good with having two peppies, which is good cause 2 of my permanent villagers are peppies. I have 3 right now and it also doesn’t bother me. I am okay having 2 normals too, and and I really would like to have 2 sisterly villagers at some point.
I’m not sure about lazies, because I’m not sure if I like any of the other lazy designs enough that i want to use an additional spot for one. Never tried having two jocks, but considering it, cause there are a couple jocks I really think I would like, (such as Rory and Biff) but I am never getting rid of Genji!
I think no on snooties, smugs, and crankies. Currently, I have no cranky and may keep it that way. Kabuki is an amazing character design but I just found the personality uninteresting.
I currently have more than one smug but I like their personality so much I have no thoughts of removing either of them. At one point I had two puppies but I really started to drive me crazy and I kept hearing over and over how they wanted to be famous.
I could have two of any except for jock and peppy, my absolute least favourite personalities by far. If I wasn’t so into having it all equal I’d have 3 uchi, 3 snooty and 1 of everything else with no jock or peppy
Currently I have two cranky and two lazy villagers. I love them!
But the resident roster will change over time as I like having new animals on my island to keep things exciting. I like all the personalities except normal. (Peppy and jock types, not so much, but they are still more interesting to me than the normal personality.) So, at any point in time, I could have two or more of any personality. Except normal.
