I love Slack but Huddle is absolutely terrible. Extremely low audio quality with extreme latency (whereas I have superb quality and low latency on Meet and Zoom on same devices/connections).
It's gotten a lot better for me though latency may be a factor here. But I think it's fair to say it's still not as nice screenhero was in terms of quality and responsiveness. Which is weird because that's who they acqui-hired for creating huddles (well, presumably anyway).
huddle as a lot of limitations. it's good for random adhoc chats but not good for more formal scheduled meeting. for larger companies, using something zoom-like and huddle makes sense.
My company does not have many formal scheduled meetings. Mostly doing huddle to adhoc chat, discuss problems, screen share and pair program. It works well
