We use Hangouts Chat, Switched from Slack about a year ago. If you solely look at the utility of chat and keeping history of chat, Slack provides no benefit @ $7 a user over Hangouts if you're already a G Suite Subscriber. Slack has a cleaner interface and has much better integrations. The community of addons and bots is huge and the APIs are better. But, you can achieve all the same things with Hangouts it's just not the path most traveled. That said, If I had the choice. I would rather use Slack.
