Difficult to say really, the hanzo was just more comfortable for me - probably the slightly different geometry suited me better. You'll need to allow for putting decent pedals on it and upgrading the chain. And if you do go for the hanzo, I would suggest swapping the wheels. I went for the bullhorns as I ride my geared bike with drop bars in the way you describe. I was half-expecting to swap them but, so far, I've liked riding with them.
