I've got no experience with the others, but with the Fish Trap Pro, I've got plenty of room ( I'm 6'4" and it's all arms and legs). I keep a buddy heater, my flasher and a couple of rod holders on the ice, and still have room to stretch my legs. It's a bit hard getting in and out of the door though, the thing only comes up to my waist, but it's better than opening the whole thing and letting the heat out. Plenty of elbow room to take off a jacket, and head room when sitting down has never been an issue yet.
