I saw a graph of our local gravity wells, the moon and Mars are surprisingly similar. The moon has many extra challenges that Mars does not. Propulsively landing on a dust pile is trickier than slowing down with aerobraking.

And to land on Mars you need both, ideally. The athmosphere is too thin to rely on just aerobreaking and the other would use much more propulsion.
