The A319 is very easy to land and has a short body so you have no real worries of tailstrike in the flare unless you are doing something very wrong.
For what it is worth as a very regular passenger of Ryanair I would say their landings are average the same as every other airline. Last flight I had was 2 days ago, the pilot greased it into Luton. I struggle to grease it in there in the bus, the runway is short and has a slope at either end. I fly the A321 most of the time, it pretty much lands itself.
