The Gunks suck and are filled with too many downstate "climbers" and and New Jersey-ites anyway. Stay the hell away. Everyone should go climb at Eldo and Eldo only because it's clearly the best climbing crag in the country.
Having climbed both of these places I can say that NC in general is way better. PS. Don't forget about naked people climbing The Dangler too. It seems to be a pretty strong tradition at the Gunks
