I'll second the Summit vote. I started out gun hunting and bought the Revolution model for comfort so I could sit all day if I needed to. It was pretty heavy, so I ended up taking off the footrest bar to lighten the load a bit. Doing this turned it into basically a hand climber with no foot rest but I don't mind that.

A lot of guys on here swear by the Viper model. The bar looks as though it would get in the way, but it actually allows you to stand up, turn around, and lean against it for shots facing behind the tree. The other good part of that model is you can lower the seat down and use that bar as a gun rest.

One last thing about Summits, you can buy virtually any model(not the Goliath and maybe a few others) and use any top piece with the same foot platform. This will allow you to possibly buy an additional top piece later and maybe have multiple setups(gun vs. bow, heavy and comfortable vs. light and fast, etc)...if that's important to you. Just my two cents. Good luck, and happy hunting.
