The reason I didn't even consider Dublin over London or another major European had little to do with the rent prices as it had to do public transportation.
Being dependent on mainly in Dublin means you'll likely want to restrict yourself to areas which can get you to your workplace with zero connections (and everyone else who works in your general area will probably feel the same).
Being an especially wet country (nowhere near as bad as the west of Ireland, mind), means even this is gonna be an utter misery many mornings and evenings.
As far as nightlife is concerned, with a better public transportation system you can get away for ages by just continuing to push stuff further out.
In London I've the option if I want to live pretty far out (but still on a line that stops near my office) and live alone for not a whole lot more (if anything) than I'd pay to live within walking distance and share. Hardly anyone I know on my pay level in Dublin could even consider living alone, which puts even further pressure on living as near to work as possible.
