I'd look for the most versatile suite that has all the qualities YOU are looking for. Wind proof, water proof, zip out liners, for the widest range of temperatures and weather you're going to hunt in. I've got an older Scent Blocker suite and I hate the leg zippers. They're inside of the legs and only knee to ankle. To walk with the zippers open is a pain and I have to take my boots off to get pants on or off. Major pain. Pockets are important. One pair of hunting pants I have has no back pockets. Bummer. Scentblocker leg pockets are cool with the sit down zipper opening on the side and flap on top opening, great idea. Removable jacket hood? Hide away jacket hood or no hood? and the little things like will your sell phone really fit in that cell phone pocket? Can you shoot your bow without a bulky sleeve in the way? My Scentblocker jacket has a built in archery arm guard. Nice touch.
I'd look for all the comfort qualities and if it happens to be on a carbon suit, all the better. Being scent free wont stop hypothermia from being wet or cold.
