firstly happy new year for all.

I need to start use Matrix to talk with my biggest friends and colleagues of my university, but i read is good not create an account on matrix.org and create an account in others public servers , to not centralize the matrix protocol. My question is if anyone has a good experience with others public servers, besides matrix.org. Any tip or advice?

I found this servers on joinmatrix with longstanding: https://tchncs.de/en/matrix | https://syscom.utwente.io/info/matrix/homeserver/ | https://matrix-help.envs.net/ | https://tedomum.net/service/matrix/ | https://rollenspiel.chat/ …

Which one should i choose, any tip?
