I think any of the Eneloop family is the gold standard for AA NiMHs. Some have a bit more power, but less cycles.
I also feel the charger makes a difference, dumb vs. smart. You can balance charge time, heat & cell life, and the charger should use the dV/dt charge sensing and be reliable at detecting end of charge.
Personally, I use a Maha-Powerex MH-C9000, although there are several others well thought of. My understanding is that the charge rate should optimally be about 0.5-1C, so a 2000mAh Eneloop should be charged at 1000mA-2000mA. I understand that this Maha undercharges slightly and does a tiny trickle charge after it says, "full," but never totally shuts off. You are supposed to remove the cells after an overnight charge & sit, I guess.
