Neither of the above imo, though they're very similar. I use eFest 18350s personally and have had no problems.

Panasonic CGR18650CH 2250mAh Hybrid batteries are what I swear by for long-mode. Be sure to get flat tops as the button tops wont fit in most mods except maybe the Vamo/Similar. None of the Panasonics will fit in a Provari.

I'd go with AW over Efest even if it costs a little more. In my book, they're simply better quality batteries and hold their capabilities longer.

im asking about efest batts because i have two aw imr and after 1 month of daily usage, one of the aw imr is not working anymore, the other one loses its volts very fast.

I've used the gray Pansonic CGR18650's for months.....they last longer then my AW 18650's or my Efest 18650's, all 3 own my 3100 mah Trustfire 18650's.

You must have a cheap battery charger or a bad battery. Pannys seem the best among the 18650's for battery life here.

All of my 18650's are at least 3 months old (have 7).....none have died.

You need a battery recharger. Nitecore Intellicharger i4

My AW IMR's hold their voltage well even after a few hundred cycles, best I've found. That said, Efests have gotten overall good reviews and I wouldn't ignore them at half the price. The plain blue wrapped and EH brands sold as IMR haven't held up well at all for me. In either case, using a reputable vendor where you can feel comfortable they are genuine is the key.
