IMHO it depends on what aircraft you are flying and how fast it responds to a crosswind.
If you are in a 100 tonne Boeing crabbing into a crosswind, you get the flare wrong and float for a few seconds down the runway then it's going to keep going more or less down the runway whenever you kick the crab straight. No problem.
If it's an ultralight, and you kick the crab straight too early, a crosswind will accelerate the aircraft sideways significantly before you arrive on the ground and leave lots of rubber on the runway.
Wing down in a light aircraft allows one to float a bit without accelerating sideways ..... even if it requires one wheeled touchdown. Obviously this argument may not suit some long winged machines.
