I like petite women but have seldom dated many. To be honest, I have never thought of as a woman's height as a factor for your question or anything. Who is more successful? I don't have a clue. I think taller might have a disadvantage in that only because some men might be shorter and it might bother one or both? The average height of women I've dated would be between 5'4" and 5'6". It wouldn't bother me if she was an inch or three taller. Personality and compatibility beat everything else out.
