Hey C. The popular answer is "its up to you". there are may folks that like both brands. Just because more people like A verses B dosent really mean anything. Its what you feel best with. My choice is Iwata. I have a couple of Dev. brushes (loved the "63) but had some trouble getting parts. thats why I went to Iwata. Can get parts down the street when needed. Cant say that for my Develibis. Just something to consider.
