When I was growing up with the films ROTJ was my favourite Star Wars film. It isn't now, but back then as a child, I enjoyed it more because it was more appealing to me as a kid mainly because of the Ewoks, Jabba the hut, the epic space battle, luke vs vader. It had so many magic moments that were special to me, just like the magic moments from other films during my childhood, such as E.T, Superman, Willow, Raiders, Goonies etc.
Watching ROTJ now older, I don't enjoy quite as much, but I do appreciate it as a decent Star Wars film despite its flaws, and while it isn't my favourite Star Wars film now (that goes to ESB), I still rank it higher than any of the PT. And for best feel good Star Wars moments, it's the movie I go to to feel like a kid again, much the same as when I go to Raiders more than any of Indy film.
