Without a doubt I would buy the PWS if it was my money.
I currently own a PWS Mk216 Mod 0 and will be getting a mod 1 upper sometime next year for the adjustable gas system.
When I was shopping for a 308 rifle I put my hands on everything I could including the scar 17. When it came to the scar, it didn't feel anywhere near the quality that it should for the price. It ran fine and everything, it just didn't feel like its build quality justified the wallet rape. It also just didn't feel like it became a part of me when running it. Some guns feel like a body part you've always had, some don't. The scar 17 felt like I had a slightly odd implant on my shoulder. I also see a lot of Scar 17's come up on the used market, I don't often see a pws 308 for sale used if that says anything about what other owners think as well.
I was more accurate with an AR platform rifle, and of all of them the PWS had what I wanted in recoil behavior due to being a long stroke piston. Stock it was softer and more fluid feeling than the other rifles I shot, and after adding a heavy buffer to it its just nice to shoot. That is without a muzzle break either. It currently just has a Triad flash hider on it because my old shooting partner bitched all the time about the concussion from the FSC30. Even without a brake it's a very pleasant rifle to shoot whether I am prone, bench or running carbine drills with it.
My only gripes have been cured with the new Mod1 versions adjustable gas and new keypad rail system.
What state are you in? If you are in az and want to shoot a PWS let me know and I'll take you out with it.
