Those aren't all my guns in the rack, but if you'd like my opinion since I have fired both:
It depends. The SCAR-H is a good gun, but you can get an piston AR for less.
Buds has SCAR's in 223/556 for about $2,499. I'd say you could easily get a piston AR w/optic for that same price.
But, there will be a million AR-15's at the range that look exactly the same. I don't think I have seen a SCAR at the range...ever.
So really you can pay for the exclusivity and the pimp factor of being the only one out there with that gun...or you can save yourself some money and go with a piston AR.
