I went with a Duralast Platinum battery. It's an AGM made by Deka in the US (out east somewhere). It's supposed to be a good battery. I've had mine for several years. It's been bounced down hundreds of miles of dirt road and trails. It helps to power a winch and a set of KC Dayliters.
Updated somewhere else, but it did not change after sitting for 2 weeks. Only weird thing is that at least from my cheapie 12v gauge after i turn off the truck, it never stays at 12.6v like others say it should. It has always dropped to 12.2-12.3v and stayed there.
