I've never had him in my town aside from the campsite when I had 10 villagers already, but I love Doc's design. I'm planning on having him in my second town when I start it.
Out of this list Erik is easily my favorite lazy! He's super cute and nice to talk to and his house is like a cabin inside and I think it's wonderful lol. Other than that, I also love Papi but he's not on the list lol
