We shifted from Slack to Hangouts Chat about 3 months ago.

It has generally gone down pretty well. It has nice features like the way it makes posts in Rooms their own 'threads', and allows the user to enable or disable notifications per 'thread'. Also, as you say, the cost for Chat was included with our G-Suite license.

However, as a SysAdmin it doesn't have the same level of administrator controls that you see in more mature products, such as Slack (and even Discord). In my opinion it is still very much in beta and Google need to keep adding to the admin and end-user features before it really competes with Slack.
