I've had Samson and Moose in my old town and they were okay but not my favorite. I was actually watching somebody's gameplay and I saw Rod and I think I remember liking him alot not because of his design either but I just felt he really clicked with me of the mouses that I've had, I can't really pinpoint why but he just stood out to me and that person's gameplay video helped in piquing my slight interest in him. I also got his Amiibo card as well which I will use if I ever need a change in villagers one day!
I've only had four mice in throughout my AC towns. In CF, Samson, Dora, Limbergh. I liked Samson the most, and hated Limbergh. Dora was ehhh, I didn't really get to know her tbh. I've only had Rizzo in NL a long time ago, and I don't really remember him tbh.
