Yes, in my opinion, it is absolutely worth it.
I am a former Bartolini Air student and I was very happy with them. I have never had a problem with them and thoroughly enjoyed my time there.
Ryanair is a great start for someone's career and if you manage to get based in a base of your choice, their 5-4 roster can give you excellent quality of life. Yes, I agree they are not the best employer around, but none is perfect.
And the new contract in Italy looks very good. I'd sign for it right now if I could.
