MistyMC is a long term 100 percent vanilla SMP that has been running for around six months. It is a no reset world so your builds and progress are meant to stick around.
The server lets Java and Bedrock players play together on the most recent versions. The community is pretty tight and active on Discord and it seems like a good place to make friends.
People join to chill with others or bring their buddies for that two week Minecraft phase. Some players also like forming nations and just living the SMP life.
There is also a Bluemap so you can look at the world map outside the game.
