DSA Fal vs M1a
I'll be a smart*ss and chime in too: get a Scar 17. Man, I always hate when people do this too!
I've had 3 FAL's, love the ergonomics, they feel great, they shoot decent, I preferred the L1A1. Irons wiggled, gas system sensitive.
I've had 2 M14-style rifles. The first one, new from Springfield, held nice tight 5" groups, scoped or irons it didn't matter. The second was a Polytech with USGI parts. It shot fantastic but no scope mount would maintain zero, SEI nor Sadlak.
The Scar 17 is much lighter, good ergos, simple but adjustable gas system, easy to mount optics, Very accurate, and 5/8-24 muzzle threads which I wanted for running suppressed. So far 100% reliable with most of my use being suppressed.
My opinions here. If I HAD to pick, I'd probably have an L1A1 built by a reputable builder as I prefer the inch rifles over metric.
