The Summit line, IMO is the best, bar none. Any of them are great and very comfortable. For pure comfort the Revolution is hard to beat. The downside is it is a little harder to climb with. The Viper is slightly less comfortable, but very easy to climb with. I own one of each and love both of them.

As far as the Lounge, it is a great stand comfort wise. I personally would not choose one for bow hunting. It is harder to assemble and set up than the Summits, and harder to climb. I do nt like the platform for bow hunting because it sticks you about 2 feet away from the tree when you stand in it. It defeats the purpose of finding some cover if you are getting that far from the tree. I also found the platform to be very small.
