I'd never thought about a favorite piece of Apollo tech, but you make a strong case: the LM is pretty amazing. The MAV will have to do all that and a lot more besides, and in a much bigger gravity well, and with an atmosphere, and for a multi-year period in an incredibly hostile, dusty environment. EDIT: Actually, I had a favorite - the F1 engine. I find the idea of needing an auxiliary gas generator rocket engine inside just to turn a fuel pump pretty amazing. Likely I'm a bit more impressed by raw power than you :)
