I don't know if I can call this the best RPG ever made but I'm also struggling to think of one I enjoyed more. RF4 may not seem stellar on the surface but when you actually play it you'll recognize the level of polish, intricacies of its systems, insane amounts of content, and wonderfully charming characters. This is easily the peak of the Rune Factory series and even Rune Factory 5 probably won't be able to top it.
