The 110TTSX over 40 grains of 4198 is the "most for the least" that you're going to get in the 308. It'll kill anything that you want to shoot back East, and most of what you'll ever hunt out West.
As to flatness and recoil, the 260-120 does not have less recoil than the 308-130 load due to needing more of a slower-burning powder than the 308 loading. The extra flatness doesn't even show up until nearly 400 yards.
Having been a 260 user since 1997 when it was commercialized by Remington, and a 308 user alongside of it, it absolutely won't do anything inside of 400 yards that you couldn't do just as easily with a 308.
In other words, outside of a couple of niche applications at the extremes of the spectrum, they both do the same thing.
