Them's fightin' words! (although Tullamore Dew is absolutely fantastic!) I've been a huge fan of Jameson for a looooooong time (*almost* talked my wife into naming my daughter Jameson. So close ). Especially their 12 year aged one. It's only like $10-15 more than their "regular" version, but MUCH smoother.
They (Jameson) also make a great bottle called "Redbreast," which I like even better than the regular 12 year stuff. Link: https://shop.jameson...ast-12-year-old
I was going to suggest RedBreast 12 for the "expensive" irish whiskey actually. Redbreast was the first more expensive Irish whiskey I ever bought. It's good stuff. If I see it on sale I pick it up. I just recently tried Glendalough and it was pretty good. Irish whiskey has never been my go to, I don't know why, I have never had an Irish whiskey do me wrong. Rye whiskey is what gets me in trouble...
Fun fact the word whiskey comes from the Irish phrase "uisce beatha", which means water of life.
