I've had no experience with the PTR/H&K-91, other than to want one because Burt Gummer carried it. But being a lefty, and not willing to shell out 4,000 bucks on a rifle kinda rules that rifle out.
I got to fire a FAL, I think it was the L1A1 variant, for familirization, and thought it was the coolest thing ever.
I would choose it over the M1A, simply because I found it more ergo-nomic, atleast for me.
Not to disparage the M1A/M-14 family at all, a great weapon system. And an accurate one.
That being said, the FN-FAl is sometimes referred to as "The right arm of the free world."
