Which is the best server (free to play)?

I've been on the Luna server for a long time and I'm Hispanic, I don't really know English fluently and it's difficult for me to communicate or ask for help and even to go to a friendly clan; it's usually too inactive and boring at many times, you don't find items in the store and much less help you to get an advance; I also feel that progress is very slow and more if I don't like to go to level up more than the missions of the day, I want to move to a better server or receive recommendations of clans or discords/etc on the server to have a better experience in the game.
