Comparing the AdvancedFrame Sport, the AdvancedFrame Ultralite and the AdvancedFrame Kayaks

They kinda look the same ... so what's the difference between the AdvancedFrame Sport, the AdvancedFrame Ultralite and the AdvancedFrame inflatable kayak?
This video compares performance on the water, set-up time, weight, capacity and price of all 3 kayaks.
If you would like me to choose for you, I just need a bit of info from you here:
