We visit both campgrounds often and one year we got snowed upon for Easter at Bethpage. Each campground offers it's own fun and nice things. Cherrystone is the only camping "on the water" with some awesome sunsets. Bethpage is a nice campground but do not recommend during festivals as they double park trailers on the lots. You are not placed on the water view sites at Bethpage as the perm folks have all of them.
Good luck on your decision and as I said both parks offer some nice things and views.
