I really like the WSM line. I have owned or still own several of them. The 270 WSM is probably my favorite. The 7mm and 300's are excellent as well.

Another thought if you're a reloader is the 6.5-284. I own one and I really am impressed with the results. I've read good reports from Wildcatters about the 6.5 WSM. The 6.5 caliber bullets really shine at the longer distances.
