Not for me, it wouldn’t be. Hmmm, I was supposed to be traditional and old-fashioned, wasn’t I? 😉
Anyway, that’s my answer. If I’m attracted to the guy and like his personality, he smells good, etc. then I want to see how he kisses. A bad kisser is usually a dealbreaker for me. Not always because you can teach someone to kiss better to a certain extent.
