mAh directly refers to the battery's capacity.
So higher the mAh rating, the longer it will last before requiring a recharge.
So yes, 2800 > 2500 > 2100 etc...
But, you also need to make sure the device supports higher rated batteries (like 2800mAh). Some devices actually work well with 2000 mAh ones.
Hope this helped.
About the brands, both Sanyo and Uniross are good.
Depends on what they have available.

I have myself bought a 4 pack of Sanyo Eneloop 2000mAH batteries and they are really amazing. I used installed a fully charged pair of them in my XBOX 360 Wireless Controller and completed entire Fable 2 game and 3 chapters of Ninja Gaiden 2. They are yet to run out of juice.

I had bad experience with Camelion 2300mAh batteries. Used Caelion them for ~2yrs with my camera. They were giving bad backup ii one year itself and they they are almost dead, cannot use it with camera, but can be used for other components requiring less powerfull batteries(like remote controller, telephone,etc)

How much worse are the Kodak 2500mAh batteries, for the average user who's not too concerned about how much charge a battery will retain after 2 months but rather more interested in how many pics he can get from a recently fully charged battery, as compared to the sanyos & the unicross' & the sonys of the world? The Kodaks with the charger cost almost half of what the latter costs. So what's the performance difference? TIA.

I have Eneloops but i dont have the sanyo charger. Is it safe to charge them with a Chamelion Charger (that i got with 4 2700MaH batteries)?

Those unfamilair with NIMH batteries should read this primer
The main difference the Eneloops offer over regular NiMH batteries is that they have a lower self-discharge. But there are other brands too which have terms like 'hybrid', 'ready to use' or 'pre-charged', these will be similar to eneloop as well. There are only five companies that make these low discharge batteries Sanyo, Gold Peak, Yuasa, Vapex and Uniross so the others are just rebadges from them.
The tradeoff (for now) with these new types of batteries is they have a lower capacity (mAh's) than the previous version, upto a third less.
The advantage these new NiMH batteries offer is you can charge them and then leave them for a while, Sanyo's claim is they lose 15% (per year) vs 1% (per day) with the regular NiMH batteries. With the non-eneloop types after three months they will be below the half mark level, so they have to be maintained more regularly. Storing them flat is bad for their capacity.
Wrt to the eneloops a Sanyo rep had replied to the author's findings with the foll
If you're going to be using any kind of NimH batteries in digital cameras which have a high current draw and run them till they are dead then after 200 cycles they will start to hold less charge. That means they reach your devices cut-off point faster and you get less pictures. They are on their way out. If you want them last longer then replace with fresh ones once they reach the half way point. NimH prefers partial discharges to full discharges.
As to what is the best battery, I'd think the most important factor when buying any batteries is their manufacturing date. The clock on a battery's life starts from the date it was born. An older battery is less likely to last as long as a more recent one. So if you notice a good deal at one place then check the date, if thats obscured or hidden in any way, then you know what you're getting
The author says he has a 10yr old Varta NiMH battery that still holds 85% of its charge which surprised me, I've never had any NiMh battery last more than two years before becoming useless.
