I has a small SLAP tear repaired - took 2 suture anchors. Had a bit of biceps tendon involvement as well. My surgeon also did a subacromial decompression and some intra-articular debridement.
I hit PT pretty hard after the surgery and did my own extra training in the gym in between. The challenge I think is to be vigilant about your PT, especially the stretching, but not to overdo it in the hopes of getting there quicker. I managed to overdo it a couple of times, which then set me back a few weeks.
I was diving again 3 or so months after surgery, but it took about 2 years before my shoulder felt fully there. You should realize that the strengthening/stretching will be necessary for life. I feel it pretty quick if I start to slack off. But if I stay with it I'm fine lifting and diving doubles, and I have good and equal motion in both shoulders - no problems with valve drills etc.
