I had to have the 360 because of previous surgeries and the scar tissue made it more difficult for my surgeon to gain clear access to the disk just from the back. The worst part of the whole thing was having both incisions. They went through my old c-section scar and that was the scar that hurt the most. However, I was pleased that he was able do the fusion and it fused very quickly. I don't think any fusion is easy. I hope your surgery goes well and you are able to get out of pain.
