I use a Loh rest w/ windage top if working the bench or shooting comp and about to aquire a Farley rest. If you are wanting to determine the true accuracy of a rifle a rest is the way to go (as well as wind flags). I personally like windage tops unless you can succesfully bag squeeze, which I can't. The rear I use a Protektor rabbit ear/codura. shooting varmints I use a bag. Personally I believe any quality rest will work once you learn to shoot from it and it's personality. I use a Loh rest only because I traded some work for it and I am going to a Farley for speed purposes when running a group.
