This server is called Altitude and it feels like a chill community survival place where people actually stay and play for a long time. It is a survival network that focuses on regular Minecraft with extra features to make things more interesting.
You can claim land to protect your builds so griefers cannot ruin your stuff. There is basic teleport like home and back so you do not spend all day walking. The server uses McMMO so you can level skills while you play and there is also a pet system so you can have your own creature follow you.
There is an economy with player shops so players can trade and build their own stores. Town style bases are supported with a custom warp plugin so you can move around to different communities on the server. There is a dynmap so you can see the world in your browser and explore from above.
PvP is optional so you do not have to fight if you just want to build and hang out. The server runs a newer version of Minecraft and they reset the world for major updates so players can enjoy fresh terrain. They also run monthly events which keep things from getting boring.
The rules are written out on their site and the server is meant for older players but anyone can join as long as they follow the rules and behave. Overall it feels like a relaxed place where you can log in after school or work build a base talk to people and slowly make the server your home.

GG.MINEWIND.NET New Server IPCrystal SMP Needs More Players 17+

Crystal SMP is a small survival server that started last week and it is looking for more players who are 17 plus and want a social place to play.
It runs on Neo Forge 1.21.1 and it keeps the mod list pretty light. It has custom world generation plus a few quality of life tweaks and some cosmetic stuff to make building look cooler. There is also sophisticated storage and a mod that adds more block variants for decorating.
People are still making nations and adding to spawn and writing lore. The server uses a loot system where loot is client side instead of shared vault style.
The rules try to keep an anarchy vibe but still stop the worst stuff. You cannot destroy progression blocks like trial vaults or end portals. You cannot raid offline players. If you want combat or a raid you have to tell the person first. Players also ask that you do not break the special loot chests.
There are about 10 plus active players daily and the moderation is fast. The community has lots of European and Asian players with North and South America growing too.

GG.MINEWIND.NET New Server IPWhitelisted Semi Vanilla With Insane Builds

I found Blithe and it is a whitelisted semi vanilla survival server with a really talented building community. When you first log in the season 10 spawn area is already super unique and it makes the whole server feel alive.
The staff and owners are experienced and they play daily. The playerbase feels more mature and you can be social or just do your own thing. It has casual players and also more hardcore players but it is not full SciCraft levels.
The server runs on high end hosting so it feels fast and reliable. There is also a live world map you can view online and it shows players in the overworld too.
On survival they use a few plugins like an armor stand editor proximity chat and mini blocks so it feels kind of like those Hermitcraft quality of life options. They also have optional membership perks to support the team and a suggested client side modpack you can download.
There are over 250 whitelisted players and the seasons run about five months. It starts busy around 30 to 50 players then slows down later in the season. They also have a linked permanent creative server that does not reset so people can build big projects test redstone make minigames or just mess around with friends.
