Without knowing what your reasons are, I'll walk you through my thought process.
That Savage .308 is already your long-range-precision-scoped rifle gig, so you don't need another. Cross off the AR-10, PTR91 and FAL. The M1A can stay because you enjoy it for the irons.
Both the AR-15 and AK47 fill in a nitch between your .22 and .308. Both cheaper to shoot than a .308 and a lot of fun.
So I'd choose between an M1A, AR15 or AK. If you check out both the AR and AK, you might fall into one of "those" camps immediately and rule one out. Then you'll be between the M1A and {AR,AK}. Two choices.
All that being said, If you can't decide on the ballistic merits of each platform, then use other factors. Do you like something easy to field strip? Easy to clean? Is accuracy the most important for THIS purchase? Is it going to double as a fictitious SHTF/Zombie/TEOTWAWKI gun? etc.
