I like Teams for a similar reason: it is replacing Skype for Business. Properly persisted group chat is a must have for remote teams, and SfB didn't really have that. Or actually it did ("chat rooms"), but it's one of those bolt-on features that requires cooperation of an administrator to set up. Impossible to get done in a big corporation. (Now if only if I could convince my colleagues to use Teams properly with N people in a channel instead of continuing to have N^2 one-to-one chats about the latest crisis...)
