Hey OP, I just did some cider with Target brand, seems identical to other store brands I've used (Walmart and Aldi and my local grocer). The one difference that might be worth noting is the country of origin stamped on the bottle. If you have feelings about what you prefer or which country makes the best apples (I don't, but I can tell my friends about their exotic drink made with real South African apples, oohlala).
And as others said, the nutrition facts will tell you useful info about sugars. You can compare apples to apples
Ive memorized that 1g sugar in 100ml is 1brix.
So if AJ has 28 g per 240ml serving...
28/ 2.4 = 11.6 brix
11.6 bx = 1.047 gravity (actually 1.0467
...I look that part up on my phone).
Not always very useful but it lives in my head until I forget it.
