Any battery made by AW, LG, Samsung, or Sony is a great battery as long as they are authentic and purchased from a reputable vendor. Choose the battery you need by the application that you'll use it. Often, this is determined by amp limit (CDR) first, and then choose the one with the highest capacity (mah) rating.
I use a pair of Sony VTC4's in rotation in my mechanical mod. I'm running 0.6 ohm coils with it. Depending upon where you buy them, Sony's can either be pricey or comparable to the other major brands. A couple of years ago the Sony VTC 4's were the top battery available for sub-ohm vaping, but Lg has taken over that distinction with their true 30 amp CDR batteries.
I used to use AW IMR batteries exclusively in my Provari's. I found them to be extremely consistant in quality. I used the older 18350, 18490, and 18650's. I don't use my Provari's much any longer because my vaping preferences have changed, but I'll never get rid of them. AW's, at least here in the States, generally are a little pricier than their counterparts from Lg and Samsung.
I use the brown LG HG2 3000mah 20A and AW 3000mah 20A batteries (married threesomes) in my RX200 regulated mod. The AW's perform identical to the Lg's; in fact Mooch suspects the AW's are re-wrapped Lg's, and since both are made in Korea, he's probably right.
I've used a pair of Samsung 25R's, and they are a very good battery. One of them inexplicably died (vented?).
