In conditions where full control of the a/c is not a worry I prefer to crab on final then about the time I flare to change to wing down. I like the buffer that wing down allows ie I can choose when to touch down & still be aligned.
If the the conditions are extreme then I crab on final & into the flare. As I yaw the a/c just before touchdown I still apply wing down although the wheel(s) usually touch before much wing down can happen. Adding wing down provides a slight buffer in gusty conditions just in case my timing is a bit off. I'll also fly it onto the ground rather than hold off so I can minimise the period of reducing speed (& therefore control) while still airborne. Quite often in Shetland I've needed to use asymmetric power to get an adequate yaw rate in gusty, 45kt x/winds due to the f%^&*ing slow & heavy handling of the Islander.
