I'm a big bipod fan - I own three Harris bipods. There are some disadvantages of them though, they are detachable, but not terribly quickly, they add weight to the gun, and are tough to use when shooting uphill/downhill. But I wouldn't be without mine - for the times when you can use it - it's a rock solid rest. I think I'd like to try some shooting stics someday, just to compare the two, but as for now, I'll stick with Harris.
