Mateus is growing at a very healthy and steady pace, I highly recommend the server. People are also generally very welcoming and inclusive. Alternatively, Siren just became a Preferred World in case you're interested in a smaller community, with a leveling boost and other nifty bonuses to leveling over there. There's a little bit of roleplay everywhere, so finding a FC like Maril suggested is definitely a good idea to help you with your decision.
