All three are equal in my heart. G1 AJ was so darling, a gentle clumsy lil pony who saved the TE ponies in the UK! In my mind, G3 AJ has a spunky personality, similar to G4 Pinkie in the way she has lots of energy and is always ready to have fun. G4 AJ is my favorite of the mane 6, I’ve always had a thing for country gals, and her down to earth hardworking nature appeals to me. Honestly I stan the entire apple family but that’s my take.
