Actually it's more be handsome, but be rich works too. Keep in mind women have a habit of turning on rich ugly guys when the cash flow dries up, look at what happened to Weinstein, Cosby and so on. They're the shallow and selfish gender after all. But you can avoid all of that if you're handsome. No woman would ever dare fuck over a good-looking guy.

Ideally, you want to be rich and handsome.
