Most important to me: Which of them is easier to self-host?
I’ve been running a Mumble server for my friends for over a decade now and I’d like… something more without having to get too technical. Mumble is literally just a single apt-get and you’re basically done, so that’s about the level of technical expertise that I bring to the table. I’ve tentatively looked into other solutions over the years but I always feel my attention drifting when the setup-tutorial covers multiple pages and starts with manually configuring some database or certificate authority or whatever. Sorry, I didn’t mean for this to get too ranty.
