@kensanata If group chats are important in the social circle to which you want to introduce one of those apps, I would't choose Signal, because group management there is still bad.
If you choose Threema, make sure you create any groups, because you're a responsible admin and will have data backups of your ID and chats.
@Nuntius Yeah, it’s mostly group stuff I need. I guess that all points toward Wire, for the moment.
