I found Stellara Servers and they are all about Minecraft server hosting that is meant to run smooth with mods and plugins and custom setups.
They say they focus on reliable hardware so lag stays low and TPS stays consistent. They also have instant setup so you can start fast and a simple control panel that sounds easy to use.
They also say support is responsive if you need help. They even offer a discount for your first month and they will answer questions about what plan makes sense for around 10 to 20 players.
