I have an R2A and the batteries I have in the camera currently say 357/303. Does anyone know if these would work? The description says LR44 (aka 357) but are these the same? Are they crap that will only last a half of a roll?

I have an R2M and I am using Energizer 357/303 batteries in it without any problems. Don't hesitate on the purchase. As far as I can tell they are equivalents.

The best camera is one that still works!
The best choice for voltage stability is SR44.

The major difference between similar-sized batteries is the drain rate design. Some are designed for higher rates of discharge and others for slower or steadier rates.
Using a battery for one discharge rate in another device or application probably won't be harmful, but you may not get optimum life out of that battery.
Silver oxide batteries provide good life/usage as Keith noted above. They tend to hold a very steady charge then fall off the cliff going from OK to dead very quickly. The MS76/SR44 (different mfr designation for the same battery, more or less), work well in photo applications.
You may also substitute a 1/3N lithium battery in a normal 2-battery setup without any difficulty, usually. The lithium battery has the major advantage of not leaking nor swelling like the MS76 and SR44's do at the end of their life. It also tends to have better low temperature performance, longer shelf life - up to 10 years, and may be a bit cheaper than the 2 battery setup.
