Atlas, Modular evolution, the new Thunderbeast, Cadex Falcon lite (very expensive), and Hatch are all good. I used to run several different Harris bipods but I've since moved away from them.
A lot depends on the terrain that you're hunting. For versatility I'd say either the Hatch or Modular Evolution are best. I carry a short bipod on my gun but you need a "clean" shooting area to use it...no sage brush, tall grass, etc. Since I carry a tripod for my spotting scope and binoculars I also have the ability to attach my gun to the tripod if the vegetation is too high for the bipod.
