It all came down to comfort and personal preference to me. I sat on each at a big dealer that sold all 4 jap makes. The Honda fit me the best and I am glad I got it. I wouldn't trade my F4i for anything now. And there is a big difference between Katanas (sport touring) and real sport bikes. One is not better than the other, it just depends on what you want to do with it. Buy what you need and ride safe.
