I suppose the bottom line is 3 pointing lands the plane at the lowest possible air speed, so this is the most stable way to make a landing.
As Mark mentioned the 3 point attitude gives a wing incidence of about 9 degrees, the wings will stall at 17 degrees, so the planes not close to the stall at 3 pointing speed. If I wheel on and dump it down too hard, she will leap back into the air as the CG being behind the main wheels will cause the plane to nose up, and as I still have flying speed she may get several feet into the air. This tends to lead low time pilots to lower the nose further with the inevitable crunching result. If I 3 point and dump it down too hard, it may still bounce, but there is very little flight left in the bird, the only energy to launch the plane back into the air is the springs in the undercarriage. I take the point that wheeling on gives the pilot a better view over the nose, but ground loops tend to happen at much lower speed - when the rudder runs out of authority, so all that happens is the pilot delays the ground loop. I also take the point that it is easier to judge the height when you can see over the nose, but that's not to say you cannot fly down into ground effect, and then just keep bringing the stick back so that the nose comes up as the speed bleeds off and you sink on to all 3 wheels. I know easier said than done !!
