I hate smugs but apparently O'Hare is a smug ? He just recently moved into my 1/1 Challenge town and i like him and I used to have Eugene in my old town i loved him
Lionel is my favorite Smug, mostly because I think his older-gentleman appearance suits the Smug personality much better than the younger look/feel of most of the other Smugs, like Marshal. I disliked Ed (my Smug before Lionel) because his personality rubbed me the wrong way, but with Lionel, the Smug dialogue seems less obnoxious/flirtatious and more like a posh old British man.
I've got Ken in my new town, and I actually like him more than I thought I would when I first saw he was moving in. I also tend to dislike smug villagers.
I had Olaf at one point in my old town and liked him fine, but I prefer Ken I think. I love the anteaters though so that may have been part of my affection for him. I had Pietro in that town, too, and his personality didn't bother me but I found the clown makeup distracting... haha. Which is a shame because I really love how colorful he is!
