Raymond and Sherb are both dreamies of mine and they’re popular; traded for Raymond and found Sherb on a mystery island. Rosie, Marshal, Ankha are also my dreamies who I think were fairly popular at least in NL. I found Rosie on a mystery island but haven’t found Marshal and Ankha yet.
I honestly don’t know who is popular aside from Raymond and Judy, same back in NL since I have always never been interested in popularity and whether or not my favorite villagers were popular. I passed on Dom and I’m pretty sure I passed on Sherb before he grew on me. I like villagers based on design, personality and/or time spent bonding with them. I admit some villagers grew on me because I liked a lot of the positivity and pictures posted of the villager, like Sherb

. I also admit that I sometimes do not care about or pay as much attention to some villagers as I do with other villagers, which is why I really love hearing about people’s own experiences even with villagers whose design I initially was not impressed with or even disliked, along with pictures.
My other dreamies are Punchy, Kiki, Merry, Roscoe, Lolly (never had her but really want), Rudy (another new one and was my starter; kicked him and his bad starter [ware]house with amiibo and reinvited him right away).
I invited Punchy, Kiki, Roscoe with an amiibo card which I regret since it took away some of the fun that comes with meeting new villagers as well as finding my faves on a mystery island or as a random move in. I found Merry on a mystery island but kicked my original Merry out to reinvite with her card because she would not get rid of a black bass in her house that I gave her and regretted giving her.
Lily was one of my first four villagers and I found her on a mystery island thinking she would be only temporary but later she grew on me, which is why it is going to be tough to let her go.
My other favorites that I’m not sure if they’re dreamies or not are: Puddles - my best girl villager friend in NL, Lily - I think I like Lily now even more than Puddles though sadly I am going to let her leave for Lolly (and she still has starter house that I’m not a fan of), Gaston - initially didn’t like him in NL but I am happy to say he grew on me so much (I guess he can be considered a dreamie but not as high as the cats on my list).
I could go on about villagers I like and would like to have even temporarily, but I’ll stop here since I’ll never stop babbling if I continue lol.
Sorry that the post ended up being longer than what you probably were looking for. ><
