I have both rifles in 6.5 Creedmoor.

The Ruger has been consistently more accurate, but the Mossberg still shoots less than 2 MOA groups at 100 yards with the Winchester/Olin 125 grain Deer Season XP factory loads. I like the stock and magazine design better on the Mossberg Patriot. Since I have hands on experience with both rifles, I'd probably buy the Mossberg and spend the $200 on optics.
