I have an antirock. I don't have to touch anything.
On the Swayloc, I think most here go for the manual option. I guess it depends on if getting out and moving a lever is too much of a hassle or you prefer to hit a switch from the drivers seat.
I don't know what comes with the swayloc but the links from the arms to the axle and the link ends likely have length to accommodate a 6" lift.
I also have an AntiRock but only because the SwayLOC wasn't around when I built my Jeep out the first time. My impression is most go for the manual operation because it's one less thing to break, easy enough, and cheaper. I'd do the same.
