To me it doesn't matter. Beauty fades within time anyway. If the person is annoying as fuck it doesn't matter how good they look imo.
Since society pressures it though, I'd rather be a beautiful girl rather than a cute one. Cute girls are usually seen as the 'little sister' types / not in a romantic light.
Beautiful. Cute is nice and all, but nothing beats that feeling of satisfaction and pride when you look at your gf and go "Damn...She's just beautiful. Lucky me."
