Best Ragnarok to play

I used to play eternal love, and knew nothing about the franchise. I know eternal love is still online but I've heard it's p2w these days. So my question is what's the best ragnorak game to play? It's kind of overwhelmeing as there's so many mobile ragnarok games, and apparently an upcoming eternal love 2 that looks really cool. I don't know if there's one main ragnarok game and the rest are side games or if each has its own community or what, but I'm just kind of confused on why there's so many lol
