In dating is it better to have a lot in common or not much at all?

I had a girl tell me it was better to have nothing in common and that it would give you more to talk about. But logically wouldn’t having more in common be better? I’d feel like having a lot of shared interests would give you more to talk about an more things you could do together rather then very little. But then they do say opposites attract so have you had better experiences with girls you share a lot of interests with or better with girls you haven’t? Especially when it comes to conversation?
