Welcome aboard. I had open surgery by choice, and can make good arguments for that type of treatment. Most of the surgery guys here had robotic. One thing we agree upon, is the method of surgery is second, to the experience level of the surgeon.
With as many positive cores as your biopsy indicates, and being dx. at Gleason 7, I believe surgery is a good fit for you, either variation.
Good luck as you come to your own decision. As clock said above, if you didn't have anxiety about the decision, we would be more worried. You will do fine.
