It has nothing to do with their skill, as has already been established.
Smooth touchdowns are not the key to a safe landing, I'd rather have a very hard landing that is perfectly safe than a very smooth landing which isn't safe at all.
It has nothing to do with airline either, I've had horrible landings with Ryanair and I've also had some of the best.. Either way, I don't criticize or praise the crew for it, whatever the outcome of the touchdown is - It was safe and thats what they are there to do, safely fly the aircraft.
I've had worse landings with Emirates than I have Ryanair, haha.
