Small asymmetric edges are easy to use if you're a lefty so don't worry about that too much if at all.
The hiro has the best steel of the group. If it were me personally I would try something hand made like this Masakage Yuki. I love this knife:http://www.chefknivestogo.com/mayugy24.html
I like it better than all the knives you listed. That said it's more money than all the knives you listed. It's hand made, with a sick edge on it right out of the box. The steel and heat treat are very good and the handle is nice. Beautiful knife and excellent performance in a knife that has some soul to it.
