I clearly cannot comment on the "best"

I began using 500 mA Hour nicad's with my AF500FTZ, and migrated to Nickel Metal Hydride batteries as they became available.

I have a collection of Nickel Metal Hydride batteries that I use presently with my AF500FTZ and AF540FGZ flashes (they use about the same amount of power) ranging from 1200mA hour (quite old now) through 1600, 1900, 2100 mA Hour.

The only difference I see is in terms of number of flashes.

Note I use these batteries also in my *istD.

2500+ NiMh produce the best results for Rechargable Batteries. The only downfall is you must use them w/in a week of charging or they self-discharge too much. (I Like the Enegiser 2500 you can buy at wallmart for like $13 for 8)
I also keep a set of 2100 Enloops in the one flash so I know I have good batteries in atleast 1 flash. I also have a set of these as my "back-up" set in my bag. These are more expensive ($10+ for 8 and hard to find outside of a ritz camera)

2500 mAh batteries are becoming a minimum standard of sorts. If you're out buying new batteries, don't bother buying anything lower as it's not worth it. Lower mAh batteries will not be any cheaper anyway so might as well get the most.

Energizer batteries are good. Walmart has another brand, Digital something-or-other which are equally good, maybe $2 cheaper.

I have 4 different brands at the moment (my oldest set is close to 7 yrs and they're still going strong), but I save the newest/strongest ones for my more critical needs (flashes). The older ones are the last resort batteries and they've saved me more than once. They still last me a long time too, so there's no need to replace them. I just keep adding to the collection!

Add to that three different but compatible chargers and I can keep all my batteries quite happy :-)

In my 540 I use Ansmann's 2100 mAh. They are the same type as Eneloops, which are not easy to find here. I get 100 flash shots with them, easy.
