I found Stellara Servers and it looks like a solid pick if you want a Minecraft server that runs smooth even when you use mods or plugins.
It seems built for low lag and stable TPS with fast hardware. They also support modpacks and plugins and custom jars so you can set it up how you want.
The control panel is supposed to be simple and the setup is instant so you can get playing fast. Support also sounds helpful and responsive.
They even mention a 60 percent off first month deal with the code REDDIT60 if you want to try it without paying a lot at the start.
