Unless I made an incorrect calculation neither of these rifles will recoil more than 20 ft/lb. with a copy of the GAP Xtreme hunter rifle which weighs 9 lb.
IMO you don't need a brake for a hunting rifle that has such low recoil..
The cool factor goes to the 6.5 Gap cartridge but the 7 SAUM is no slouch either. The 7 SAUM is one of the 1000 yd BR darlings and for good reason.
