In my opinion
1) It's the most important thing. Bar none. Sure they're a lot of other factors; common interests, compatible senses of humor, etc; but if I'm not attracted to him, it's not gonna work.
But what happens if and when that attraction (specifically referring to physical attraction) leaves? Wrinkles and love handles appear, things start to sag, people get into disfiguring accidents, etc. If the other aspects of a successful relationship are secondary, then there is a better chance the relationship will end (and end badly) when the physical attraction is gone. If those other things are primary, though, there is a much stronger and longer-lasting foundation. This does not mean that physical attraction is not important, it just means it should not be at the top of your list.
Also, if it is known to the other that you like them most because of their physical attributes, that can lead to them wondering what would happen if someone more physically attractive comes along? It leads to insecurity and a focus on not who the person is, but on how they look.
