The answer is the same either way, for two reasons:
As for connection times, you're flying Ryanair, and you may have to change terminals. If your flight is late, or you are late and miss it for some reason, you are responsible for the costs. If this might be a problem for you, I'd allow plenty of connection time (e.g. 2 hours or more), or book a single ticket, and/or fly through a different airport. You can almost certainly get away with a shorter connection, but it does get risky. For an EU national, an hour or less is certainly possible if all goes well. If all doesn't go well, you could lose a lot of money.
