I bought a quad of Radio Shack NiMH AA batteries and their charger in December 1999. I have recharged these batteries at least 150 times each and they still work very well in my Sony Walkman cassette. These are the gold colored 1200 mAH version. Their current model is 1800mAH and is colored metallic green.
I later purchased (on sale) several quads of Panasonic NiMH AAs, and I have been disappointed. They are 1800mAH suppposedly, but do not hold a charge as well as the Radio Shack ones.
There does seem to be a difference on various brands. The next ones I buy will be Radio Shack, even though they are not the cheapest.
I have used NiCad as well as rechargeable alkaline, and NiMH is clearly superior.
