When I first started travelling, I flew United frequently because I liked the way the livery looked compared to AA or DL. Now I think I'm more objective.

In the UA forum there's a post about how ugly the A318. The thread comments about E-jets (Embraer 170?). Ugliness doesn't affect my opinion since I know that price and engineering considerations influence aircraft purchase, not beauty.

Does a livery affect your perception of an airline? - me: not any more
What jets do you think are pretty or ugly? - me: pretty-Concorde, VC-10, 767-300, F100, IL86
ugly-ERJ145, Tu134, Comet 4B, 737-400
