I don't know about useful, but taxying into stand with all the duty free bottles rolling around the aisles after you've just popped open all the overhead lockers with your ham fistedness is not something you'll want to repeat.
We all aim to get it on as smoothly as we can, but remember that you don't always have the luxury of a long, long runway with a steady breeze coming straight at your nose.
If the runway's wet for example, you'll be aiming for a 'positive' touchdown to give you plenty of room to stop. Any fool can float the thing to a featherlike touchdown as long as you don't mind a stroll through the grass to get to the terminal after you've run off the other end.
Also some aircraft give a smoother landing than others anyway - especially those with trailing gears. The VC10 was famed for soft landings and I've always found the 747 to be the same.
