Love. Looks are important to an extent though... You do have to be attracted to someone at least a little bit. I've been with a couple of guys who were extremely attractive. Like model attractive. But their personalities made it hard to love them and I felt empty, so I broke it off. I have also dated a guy who was a good guy but was not attractive to me. It was nice to have intelligent conversations with someone but that's really all we had. I kept trying to look past it but in the end the lack of intimacy made me feel lonely and I had to break it off.
Do keep in mind, though, that sometimes someone's personality can actually make them physically attractive to you. I knew a guy who wasn't conventionally attractive and I wasn't attracted to him when I first met him but as I got to know him, and how great and funny he was, I found myself to be physically attracted to him and thought he was cute.

Both are important but the personality (which includes love) is more important for me.
