Atropolis is a newly opened SMP that is aiming for a 16+ semi vanilla community feel. It is whitelisted so people are trying to keep it chill and not random.
It stays close to vanilla but adds some quality of life stuff like phantoms being disabled and a one person sleep option. There is also a PvP toggle and some anti grief stuff on certain mobs.
If something goes wrong there are protections and rollbacks ready for worst case moments. Keep inventory is on in the nether and the end which makes risky trips way less painful.
The server uses some add ons like Simple Voicechat if you want it plus things like elytra trims deathcount head drops and a dynamap. Voice chat and elytra trims are optional.
For the first server event the end is locked for the first week so everyone can work toward opening day together. Nether access and nether roof travel are set up at spawn for people to use.
