I think the crab method requires more skill from the pilot.
Also, if the action of de-crab just before thouchdown is not perfect, there is a great chance of sliding with the wind, between the de-crab move and the moment when the wheels touch the ground. If there is a frontal gust wind, you may also start to float with the plane de-crabed, wich is even worst.
So, I prefer the wing down method, because it`s easier and safer, in my opinion. With strong winds, a combination of both may be required.
