That said I don't see the advantage of a tall thin rocket, even though computers make it easy to land vertically.
If it was an established planet with people already there, they could build a runway and a winged vehicle could land with no rockets or parachutes, just like the shuttle. However this isn't the most mass-efficient way to reenter and land, if you consider the mass of the wings, landing gear and associated structure. Also the first explorers could probably not land horizontally without a runway.
This leaves parachutes, rockets or some combination. It has been studied extensively for SSTO proposals and rockets vs parachutes are often fairly equal, but there's variation based on configuration specifics. However for a reentering SSTO you have the engines anyway -- you've already paid the mass penalty of getting them to orbit, so the decision is mass of additional fuel vs mass of parachutes. But with a purpose-designed lander, engines aren't already there. Therefore I'd guess parachutes would be the clear winner from a mass standpoint.
With modern computerized guidance a capsule/parachute approach can have precision landing capability. So parachutes no longer imply inaccurate landings.
