I already have a Scott's on one bike and an RTT on another, with the 22mm T clamps a damper is not as needed as it was before, other than for clipping a tree in 3rd, or the China rock you don't see tapped in 4th, it's bling.
The Berg damper is 1/2 the size of the Scott's and 1/4 the size of a GPR, but if it dampens back to center it's not worth the money.
