Dan it has nothing to do with time pressures. Landing an aircraft takes a considerable amount of skill - in tough weather conditions, even more so. When the runway is very wet, a landing that you can feel is desirable in order to ensure a good purchase on the ground, so as to avoid aquaplaning. It may be a short runway, in which case floating above it for a while is clearly undesirable. Furthermore, there are schools of thought that say all landings should be positive rather than smooth. Your position in the aircraft will also influence how you perceive the hardness of the landing.
One thing that is possible (although this goes for any airline) is that it was landined by a new pilot - either to commercial aviation or to the type of aircraft. It's perhaps more likely at Ryanair than another carrier, given their growth and their recruiting policies.
