Provim is a semi vanilla SMP that tries to keep the classic Minecraft feeling but adds custom stuff that still fits in. The custom features are made by their own team for this server.
You can rank up by playing and it is not pay to win. It feels like you get rewarded for sticking around and putting in time.
There is also a Story Mode adventure across islands with quests and secrets. It works if you want to explore alone or bring friends.
If you want something harder there is a Challenge Isle with custom bosses and tougher fights. The server also runs frequent events like Capture the Flag PvP tournaments and Spleef so the community has stuff to do together.

GG.MINEWIND.NET New Server IPCobblemon Ranked Battles Done Right

Cobblemon Champions is a Cobblemon server that is built around competitive balance while still being social and fun. It does not let battles turn into a mess from power creep or wallet wins.
The big thing here is a custom points based system where every Pokemon has a point value. You build teams to fit a seasonal cap and right now Season 3 is live with a 38 point cap so fights stay fair and creative.
There are player run gyms plus an Elite 4 with real rules and real stakes. Gyms rotate by season and progression is meant to feel meaningful.
If you like organized play they run draft leagues and tournaments with weekly battles playoffs and championship events. PvE content like raids bosses monuments and events is made to help you build better teams instead of just AFK farming.
They also keep perks cosmetic and quality of life only so competitive integrity stays the main rule.
