It's going to vary slightly from one aircraft to another. But in general, I would agree that wheeling it on is best in a crosswind or any kind of gusts.
ToryBoy - it is possible to do a 3-point landing with a wing down. You land with the into-wind main wheel and the tailwheel touching down simultaneously, followed by the downwind wheel. (So it's not actually a 3-point landing then, is it?!?) The reason I prefer not to is that the wheel landing allows me to keep the speed up a little bit, and choose the exact point at which I want the wheels to touch... whereas with a 3-point landing, once you've rounded out, there's nothing more you can do to affect the landing except for wait until it reaches the correct attitude and speed. At least, that's what I found in the PA18, which is the only tail-wheel aircraft I have any real experience of which has enough prop clearance to be able to wheel it on.
