It depends if you're measuring quantity of "it rains" in mm of rainfall per year, or percentage of wet time per year.
Some places are very wet by the first metric, but mostly dry by the second. I haven't spent a lot of time in Ireland, but it seemed to be the other way around.
And in general terms, Ireland has less extreme weather than the England: it's typically warmer and with less ice/snow in the winter but not as hot in the summer.
