Ryan air has a reputation for hard landings, watching this video at the 2:22 mark and reading the subsequent comments (along with personal experience) suggests many people find the landing with Ryan air much less-smooth in general than other airlines such as Easyjet.
What is the reason for this, is it a difference in the software (i.e auto-land) or some difference between Boeing and Airbus that makes Boeing's harder to land smoothly?
Some entertaining comments from the video:
A smooth landing costs extra, like everything else on this plane.
Ryanair - "We pay for maintenance so we will use maintenance"
That music was to celebrate that the landing gear hadn't been completely destroyed.
NB: Their only entry in the Accidents and Incidents section of Wikipedia is for a non-fatal bird strike incident, so I'm not suggesting they are a dangerous airline to fly with.
