Au contraire, that would be saying the objective of a good landing is 'smoothness' as measured by the punters.
Which you know it isn't, my point was that the 800 seems to present a subjectively 'harder' touchdown, when used with appropriate technique, than the rest of 737 family. I haven't flown the 900, but I hear that is much better in this regard - certainly the 700 is.
We all love a greaser, even though we know it doesn't mean anything. Especially in the 800 it often seems more to do with the alignment of Saturn than whatever faffing you did to the controls.
