That was the case, at my previous workplace. We tried both Slack and Team but decided to go with Slack. We first started with Slack and found the custom emojis extremely useful, usually for indicating specific actions or status of a thread. Later on, when we had to decide between the two, most engineers and non-engineers wanted Slack.

Also I found the slack UI/UX to be far more pleasant and inviting and more fun than Teams. I don't know why, but something seems to be off in the UI/UX for Teams.
