Small or medium-sized Mastodon instances?

I’m looking to move to a new Mastodon instance, away from Mastodon.social. I don’t have any problems with .social, but I kinda want to keep things decentralized in the Fediverse, and I want to start fresh with a new account regardless.

So, what small-to-medium size Mastodon instances do you recommend? I’m looking for something fairly general-purpose, but also keeps up to date on the latest software fairly quickly (if possible).
