Ok, so while I was waiting for a response, I did some research. I ended up going with the most affordable product on Amazon with a solid rating (4.5 star) that had a combination of various products in it. From all the research I did, it seems like different people respond to various products differently, so it all depends on the individual as far as what's best for them.

With that said, the one I went with seems to have all the main products out there that seem to work best. It's from Arazo Nutrition and has:
Glucosamine
Chondroitin
Msm
Turmeric
Boswellia

While I just started it two days ago, it has already given me some relief. In the mornings, as I'd lift my left arm to put my shirt on, there would be a bit of achiness in my shoulder (less in the right, but a slight bit). After the first day of this product, it was noticeably less. This morning, almost nothing at all. Definitely making a difference. Still sucks during my shoulder workouts, but hoping in time, it will keep improving.

Anyway, figured I would throw this update out there for anyone else in a similar predicament.
