High wing airplanes are harder to land, in my opinion, but landing a low-winger can be tricky for a pilot who has only flown high-wingers.
In cessnas the roundout and flare are more deliberate and prolonged. You have to keep adjusting the amount of back pressure or you will get a 3-point or nose first landing. Good landings are often made with the stall horn sounding and main wheels touching simultaneously. The trick is to find that happy medium between landing nose first and rounding out too high. Low-wing airplanes need to carry a bit more speed all the way to the ground, and have more of a floating tendency in ground effect (wings closer to the ground). In the hersehy-bar wing pipers you can chop the power and maintain a relatively constant amount of back pressure on the yoke, the airplane will float in ground effect and touch down smoothly. In cessnas, you will be constantly adjusting and increasing back pressure in the flare, and it's not uncommon to hit the rearward limit of yoke movement.
