I think the Atlantic Coast is great, but an acquired taste. It's very different to Sharpnose, which is a popular, convenient crag where everything is user-friendly and straightforward and you can tick loads of routes without much worry.
At Pentire, I've only done Darkinbad on second. Amazing route, but we felt that the place had a bit of an atmosphere and although Eroica had been on my ticklist for a while, we weren't rushing back to climb more routes on that wall. Worth a visit? Yes, without a doubt. Another Sharpnose? Absolutely not.
The other crag we visited was Carn Gowla, where we did Mercury and America. I thought both were amazing routes, but I had a bit of an unpleasant shock on Mercury when I discovered that some of the route is a South Stack style chossfest. Footholds breaking off on a slab isn't that much fun IMO. But it isn't quite as bad as it sounds. The top pitch of America is absolutely amazing, but it's pretty hardcore on the adventurousness side of things: questionable rock coated in guano is order of the day. Perverse, but incredible none the less.
So yes I think those crags are definitely worth a visit, but with a mindset to go to do specific 'big' routes. Romping up lovely clean walls covered in jugs, with 2 for 1 on the E-points a la Sharpnose ain't the vibe down there!
