Yes, I like Mattermost quite a bit. I have a self-hosted instance for a few friends and me. That said, it's a bit of a nag and constantly tries to upsell you to the paid version. I guess I could build my own from source with the nagging removed, but that seems like a big hassle compared to downloading the pre-built binaries.
The Mattermost user experience is quite similar to Slack, but without Slack's anti-features.
