I travelled back from Malaga (AGP) to Stansted on Saturday 17th July in EI-HGO - the newest of the fleet. It was probably the best flight I have had on Ryanair. I estimate the load factor to have been about 50% so both the current wife and I had 3 seats to ourselves each. The seats were thinner, but still comfortable for a 2.5 hour flight. Still had the "new plane" smell. The toilet was noticeably smaller and the seatbelt length was exactly the same as on the older model we travelled out on 10 days before. We left a couple of minutes early and landed 20 mins early which was a result. Hardly any queue at STN so, from wheels down to getting in my car was 30 minutes.
What was interesting was the safety card on the seat back - it shows 2 versions of the aircraft - one with 10 exits and one with 8 exits.

It looks like the rearmost doors cannot be used in the event of a water landing.
