If you ask me, definitely Just Dance 2016. It's the brightest and most colorful JD out of those you mentioned. Personally I like its tracklist the best. Even though there are less alternative routines, there is pretty enough content for you, your friends and family to have fun for weeks. There's also World Dance Floor, which is not available on JD4, and is free on PS3 if I'm not mistaken.
