For Powered Parachutes it (the difference) is quite significant. To "stop" - let the parachute come to rest on the ground - requires engine off before the chute lands, proper control of the chute to ensure it stays down, then you must get out of cockpit, set into wind, correct layout of the chute, (preflight check), startup, manoeuvre chute to take-off position, then go. (i.e. it is a separate flight) ... a touch and go - least two or all three wheels down, keeping parachute under control so that it is still in take-off position allowing for any cross-wind.
