If you have a choice, would you switch from Rite Aid to Walgreens if you learned that the Walgreens in your area prescribes Global Pharm's Sandoz?

I learned for example that the Rite Aid in my area only gives Teva/Actavis, but they're as close to Sandoz'.

Everything else will either have Lannett or worse, Mallinckrodt. Everyone hates the latter.

For me Sandoz was as close to the brand, it was a miracle & helped me through two finals. Teva doesn't seem to bad but it's like a placebo. Last thought is that maybe all generics including brand are just now watered down.. Is it possible to figure out which generic manufacturers Rite Aid and Walgreens work with? Is it worth the bother if one carries Sandoz?
