I liked the Hornady Customs in my 7MM RM. This past year I went back to the Core-Locts. My gun liked them better than the premium brands! I did not like their preformance on game though.
I will probably try the Win. Supremes this year or go back to the Hornady.
You just have to find one that works well for your gun. My 7MM just happens to like the cheaper stuff, while my .308 has a little more expensive taste!
