Ryanair use the same jets as other rival airlines, just different livery so in that respect they are no different . Even more important their safety recored is good and they almost always get you to your destination on time .
You just have to play them at their own game, check double check then triple check before hitting the button. They are cheap and cheerful and do the job.
Just be aware if you decide to be a "no show" ie cancelling a flight , and it's a return journey, you can't book a one way in the hope of using the original return . They will cancel both . Happened to someone we know. It was cheaper rebook rather than pay the adjustment fees, but they they discovered they couldn't check in for the return flight as they hadn't turned up for the first one ! They then had to book another .

never again. We didn't tell them we would not use the return, so they could not re-sell it.
