I have used many brands, many are excellent, like MAHA, but ended up using the enloops. The reason is that they don't self discharge and can sit for a year and still have a lot of the charge left. That means that they are ready to go when you grab your flash, and you do not have to wait and recharge a set uf almost depleted batteries to get started. I have about 40 of them, and use them in all kinds of electronic equipment.
Eneloop has a new higher capacity version, but I still am using my original ones that are up to three years old. Costco is a good place to buy them, or Thomas Distributing online.
