I found a Minecraft hosting option called Stellara Servers and it is made for people who want their server to run smooth. It seems like a good pick if you are starting fresh or switching hosts.
They talk a lot about fast hardware so you get low lag and stable TPS even when you use mods and plugins. They also say it works with modpacks and custom jars so it sounds flexible.
Setup is instant so you can get going fast. The control panel is supposed to be simple and they say support is helpful and responds quick.
There is also a first month discount deal listed with a code. If you are trying to plan for like 10 to 20 players it sounds like they are open to questions about what to choose.
High Performance Hosting For Modded Servers
GG.MINEWIND.NET New Server IPChill Builder SMP With Events
This is a UK based server with players from lots of time zones so it feels alive at different hours.
It is mainly a vanilla survival place with a few light quality of life tweaks that help building but still keep the core game the same.
They run regular community events like movie nights and game nights so there is usually something to do with other people.
They also use simple voice chat and their Discord stays active with chats and voice calls.
The whole vibe is friendly and welcoming and they want long term players who like building and hanging out.GG.MINEWIND.NET New Server IP
