Onion SMP is a survival server that is growing fast and it works for chill players and also grinders.
I saw that you can use claims so your builds stay protected. There are duels that are meant to be fair so you can prove your skill. It also has keep inventory so PvP is not as painful.
There is a green zone where you can relax and trade safely. There is also a red zone where you take more risks and combat logging gets punished.
You can use RTP to find fresh land and you can team up with friends using teams. It feels like a place where you can make your own story.

GG.MINEWIND.NET New Server IPUK Survival Stress Test Server
I found a brand new UK survival server that is mainly here for stress testing and performance checks. The owner is mixing Azure hosting with Minecraft and wants players to jump in and see how it feels.
It runs on Paper 1.21 and the gamemode is Survival. The server is hosted in the UK on Azure UK South so it should feel snappy for UK players.
If you join the test server you are basically helping them push the infrastructure and report if anything feels laggy or weird. They also offer free 48 hour server trials for anyone who wants to try running their own server.GG.MINEWIND.NET New Server IP
