Yeah, not surprising to see Dublin surface in a good weather list built off temperatures alone, and yet the weather is piss poor for 49/52 weeks a year.
Of the places I've been Dublin has the most stable weather except perhaps Canary islands, but the difference is that Dublin has stable and shitty weather while Canary islands have stable and nice.
I currently live in Dublin, I think you are exaggerating quite a bit.
There are many reasons not to live in Dublin (poor housing quality / price, high cost of living, poor public transport, crime, etc) but the weather is absolutely not on that list.
Dublin has about 130 rainfall days each year, and most of those are in the winter. Most days are mild and dry. The weather is warm and pleasant enough to enjoy water sports year-round. I spend most of my recreation time during the winter in a wetsuit without a hood.
We don't get heavy snow, extreme cold/heat, hurricane force winds, or flooding. Overall, I think the weather here is better than most people give it credit for.
For me the problem with Ireland's weather is the lack of sunshine. It gets about 1500 hours of sunshine a year, compared to 2500 in New York and over 3000 in California. Growing up in Ireland I didn't identify this as a problem, but after moving to the US I realized that lots of sun, even on freezing days, is just so nice.
the city center and surrounding area is very well connected, but Dublin has a large, sprawling suburban area which while connected, has very infrequent connections.
the public transit services also disappears for almost all intended purposes at night, which is weird for a very international capital with such a vibrant night life. and taxis often refuse courses outside the inner city, albeit that has been changing with ubers and whatnot.
