A few years back a guy did agood dive into this on (other website name redacted). He said for things like digital camersand other high draw items, Duracell is still the champ - however, $/hour of use, some cgeaper bands came out ahead. I still have half a giant pack of AC Delco AA / AAAs that have been quite solid.
Here's a comparison site that graphs the voltage during discharge of a bunch of AA and AAA batteries with various loads using a high-end battery tester.
NiMH rechargeable AAs trounce every alkaline under heavy load. It's not even close at 0.5A and above. Disposable lithium is better still up to 2A, but extremely expensive. Few devices will draw more than 2A from an AA battery, but I can think of a couple of flashlights that do; disposable lithium is unsuitable for those.
