If you're talking permanently mounted power (probably hydraulic) jacks, I think the most important feature to get is "direct acting" as opposed to "kick down."
We've had two Class C's we bought used, and both had HWK kick down jacks. The biggest problem, and we had it repeatedly, was one or more jacks would extend before it kicked to vertical.
The first Class C had an individual control lever for each jack. Manufacturers went away from that setup, because it's too easy to deploy jacks in a way that racks the frame and coach body. Being aware of that, I used them carefully and it really helped me to work with a jack that wouldn't "kick."
The C we have now, has a panel with lights to tell which side or end is low. You push a button that always deploys two jacks. Both Fronts, Both Rears, Left Front and Left Rear to make Left Side, Right Front and Right Rear to make up Right side. That setup would be OK, IF the Jacks would always "kick" to vertical. Since ours don't, it's a PITA.
Jacks can be nice, but I usually use Drew's system with Carpenter's Level and Two-By lumber.
