Decker, all you need is manty tarps to build your load and you can pack anything, I grew up using both, sawbucks are nice for hauling meat in utah panniers but I liked the deckers better for work. Also if you got one side heavier than the other you can adjust how it rides on deckers easier and without repacking everything. Also with either you gotta learn hitches. Also if you want to use panniers you can on a decker, alforjas hooks make it easy.
