I found a server called NETHER.ONLINE and it is trying to be way more intense than normal survival. It is built around huge exploration and tough fighting so you always have something to do.
It has custom bosses plus a ton of biomes across all dimensions. You can also find custom structures dungeons and trial chambers which makes exploring feel massive.
There are custom items and resources that are chance based so you keep chasing better finds. They also have self flying elytra which sounds fast and wild.
The server says cheating is impossible because they use their own anti xray and anti esp. It also says there is no pay to win ever so it is supposed to stay fair.
It is a new server with constant updates and it is run by a passionate owner and a small dedicated staff team.

I found Rosedalean SMP and it feels like a chill survival server with a lively player base and a friendly community. It is made for both casual players and the people who grind a lot so you can fit in either way.
The server is all about community and creativity. Players are encouraged to share ideas help with events and join factions. You can try to become the strongest group or just relax in a cozy village with animals.
It is an 18 plus server and you have to apply to join. That helps keep things respectful and grief free. The vibe is inspired by Hermitcraft and it is enhanced vanilla with add ons so you do not need to install extra mods.
It also has simple voice chat Terralith biomes a ticket system a BlueMap and events. There are custom armor trims too and they want suggestions from players.GG.MINEWIND.NET New Server IP
