I like how Wa handles are almost weightless. All of the weight of the knife is in the blade and right over what you are cutting. Western handles feel so heavy to me now.
Another thing I like is how Wa handles allow for different grips and handling techniques. When I was trained with Western knives I learn to basically grip the blade with a pinch grip and never let go of that grip all day. Now that my knife skills have improved, I switch grips often and use grips that are suited to the task and knife. Wa handles allow this much better than Western, IMO.
And finally, I think they look way cooler.
