First, I am not involved in any way other than a user of these. They cost less than those you are asking about and work very well. Hold a charge well in storage. Read the customer reviews as some of them have really tested the batteries - a few directly against what you are asking about.
I have some PowerEx rechargeables that I have been using for more then 12 years now. A few have failed over that time. All of the everready and RayoVac I have bought have died within 2 years. The Eneloops still work after two years.
For long term in the case I would go with the Imedions and for heavy use where I am not worried about keeping them over a few months without use I would go with the PowerEx units.
Couple these with the very good chargers they offer and you have a nice combination that saves a lot over the years.
