Matrix is great as long as you know how to use it and keep it organized. It’s Element client used to mix contacts and group chats but that’s better now on web/desktop and on mobile you just need to add group chats to favorites and select the space you want to limit your browsing to (or use FluffyChat on mobile).
There’s also Zulip, which is actually closer to Slack.
If you’re on PC, use Discord as a gaming VoIP chat and you’re already using Steam I’d tell you to take a peek at Steam’s voice settings and either use that or disable Steam’s overlay if you don’t like it for whatever reason. In my experience Steam’s chat performs much better than Discord but can be trickier to configure for some.
XMPP has an experimental XEP for group spaces too, but who knows if it’ll be ready soon or used in apps for all major platforms.
