Just throwing in my two cents. I work with a small remote team and our first problem was that most apps would at times lag, hang, deliver messages out of order, etc. We found a relatively obscure app which has been solid and we have stuck with it. All other value (features) takes a hit once these issues pop up for us. There's a ton of choices out there, but if other teams are like ours, then there apparently aren't many options for this one wish-list item. If we had one more to choose from, then we might look at other features.
