Muirfield has been ranked 4th (from 9th in last years poll) best golf course in the world, according to Golf Digest, here’s the review:
4  MUIRFIELD
7,245 yards, par 71
Muirfield is universally admired as a low-key, straightforward links with fairways seemingly containing a million traffic bumps. Except for a blind tee shot on the 11th, every shot is visible and well-defined. Greens are the correct size to fit the expected iron of approach. The routing changes direction on every hole to pose different wind conditions. The front runs clockwise, the back counterclockwise, but history mistakenly credits Old Tom Morris with Muirfield’s returning nines. That was the result of H.S. Colt’s 1925 redesign.
