Pinchin the hose is cheaper and easy but a real pain for me at least. I was always holding on the bloody hose. Move a bin, hose comes with you, move a bike, hose comes with you, untangle a kink, hose comes with you, want a wee chinwag with some custies, hose comes with you. Then when I got back to the van and switched off the pump to move to next job, the excess pressure in the pole hose just spewed out when I unpinched.
Aqua-Dapter is not perfect but for me it's the most convenient way to batter on.
