All things being equal I would choose to be a bit taller. There are a few advantages that you get from it. US presidents are quite tall.
I however don't think that it's an area where you get much for the effort you put into. There are things that are much more important than your height.
I think it would be a good idea to actually date and see how women respond to your height within the context of your other attributes before you make any concrete decision.
Even if the response of the girl is positive, it still might be bad if he feels weired because she's taller then him.
I find it a bit weird to dance with girl that's taller than me. When it comes to dating girls I would prefer a girl that's shorter than me.
