My household goes through mega amounts of Double A batteries. So much that I just invested in rechargeable ones. However, for years, I used Rayovac batteries to run our Wii and toys and remote controls, etc. I believe that the name brands are better when it comes to batteries, mostly from just observing the no names last zero amount of time. I consider Rayovac a name brand, but one that is less known than the Duracell or Energizer names. It's probably because they don't advertise nearly as much. But it's also probably why you can get the same volume packs of Rayovac batteries without paying so much money. At least 20% cheaper and that adds up when you're talking about so many batteries. And as for performance, they are at least comparable to the other name brands already mentioned. I've used all of those and lots of generics and I believe Rayovac is a quality battery name and recommend using them.
