Best semi-auto .308 (7.62x51) rifle?

I own both the ptr91 & the cetme , I just use the Cetme to play around with ,the ptr (HK clone) is accurate fast reliable & it handles well (albeit a little heavy) As everyone seems to know they both chew up br & throw it a country mile I've shot the AR10 it shoots well at the range & I hear nothing but good things about the FAL FN . Even my relatively inexpensive CETME functions reliably . See if you can borrow one or two from friends & try for yourself , it's a personal thing.
