I have been to YS Falls and absolutely loved it! Havent been to Mayfield so I can not compare- Rocklands Bird Sanctuary is amazing, hummingbirds perch on your finger, my daughter LOVED it! We have been to Nine Mile, Lover's Leap, Glistening Waters, Discovery Bay It's so hard, Clarity has a great thread going with excellent suggestions, search up her thread and you will be able to get some great ideas!
