Have never used a Summit but I have a Lone Wolf Sit-n-Climb. It is a great stand but does have some drawbacks.

Pros: It is very light and easy to pack. Very easy to attach to the tree in the dark and also very quiet to get hooked on. Once set the thing is rock solid, it doesn't move or make a sound except occasionallythe seat (I'll get to that). Climbs well, easy to use. I think the best part about the stand is that it is so solid once set and you can't even get the thing to make noise, even if you try.

Cons: Comfort, this stand doesn't have it, especially if you are a big guy. I'm 6' 00' and 210 lbs and the stand is too small for me. It is not made for all day sits. It starts to get might uncomfy after 4 hrs or so. The seat can also be a problem,I don't have much room between the rails. I have to be very careful when I stand up otherwise my pants will catch a rail and pull up on the seat and then the entire seat drops. The buckles on my safety harness will also hit the seat rails and make noise.

I think by reading literature about the guy that designed the Lone Wolf, and how the stand is made, it was desinged to be easy to get in set up hunt and then get out. The Summit stands would be much better suited from a comfort standpoint. The Lone Wolf, at least IMO, is more of a specialty design. It is a great stand and well worth the money but for what it sounds like you want the Summit may be a better option.
