taildragger landing
The easiest to learn is a full stall (three pointer) landing.
Because the wheels are forward of the CG on a taildragger, touching down on the mains first ("wheel landing") will tend to increase the angle of attack and put you back in the air, if you have flying speed. Landing on the mains takes a little more finesse, I think. Once you learn it, wheel landings are better in cross winds.
Tricycle gear is a little easier, as the main wheels are rear of the CG and you will tend to "stick" to the ground.
