What was said up thread -- for SCAR H money you should be able to do a DSA folder w/16 or 18" barrel, good quality muzzle brake, put a 3-4 power ACOG on it and have money left over for a big stack of mags and ammo to go into them. If you are looking for a "battle rifle" the FAL honestly doesn't give up much to the SCAR as long as you go with one of the carbine length barrel rather than the full sized, fixed stock format.
If you want a DMR the SCAR may be better, but then again you can probably get equal performance for less money with an AR-10 and for the same money outshoot the SCAR with an AR-10 type rifle.
The main benefits of the SCAR H on the .mil side are that A) it's new and not dug out of three decades of storage, B) it's customizable for different missions (of merit for SOF, anyway, Big Army doesn't seem to grasp that concept as well), C) it's ergonomics and manual of arms are much more compatible with modern combat shooting techniques than the M-14 (but so is the FAL), and D) had we adopted both SCAR calibers, transition from one to the other, as needed, would have been pretty seamless.
It's relevance for a civilian shooter, outside the cool factor, are a little less clear, in my opinion -- though there's absolutely nothing wrong with purchasing for cool factor (and, regardless of optimal value sort of considerations, SCAR H will certainly do anything any other military style 308 will do at least just as well, if not better).
