This would boil down to personal choice. I've owned both and still have a 7mm Rem Mag. I sold the 300 WM and went a bit larger. I now have a 300 RUM. But, there's nothing wrong with the 300WM.
If you choose to stick with the 30 caliber, I would suggest you take a long look at Obermeyer's newest 5R barrels. His 30 cals are .298-.308. I have one on a 308 win in 11 twist and it has really impressed me. It is on a Sako M591 LH action and a McMillan stock.
If you decide to go 7mm, then you'll have to see what Obermeyer offers if you want his bbl. Other than that, I'd go with a Kreiger, Hart, Lothar Walther, or Bartlein
