Go, by all means
The Cliffs of Moher are famous for a reason. Go.
Just know that the car park, the ticket and the crowd three deep at the wall are only part of what's there.
What's a few minutes away

Doonagore Castle, a round tower house on the hill above Doolin, looking out over the sea. Ballinalacken Castle on its rock. Old holy wells. The cliff walk out of Doolin.
No ticket office. Most days, hardly anyone.
Do both
Do the cliffs in the morning before the coaches, then spend the afternoon on everything around them.
Put the cliffs in the middle of the map and look at what's within five miles. You'll do more in an afternoon than most visitors do in a week.
