As someone who migrated to Discord from Skype, I found it a major convenience since the big blue S seemed to screw with its interface more and more to the point where it just became an unrecognizable mess. At that point, I had had enough since I'm the type of person who wants to see everything right there in one place and not have to be bogged down like 95% of the time if I'm in a game with someone. Of course, voice quality is a bit of a concern since there are times when it cuts in and out - since you know, I'm a contributor for a podcast in one server - but I think this largely depends on where everyone's connecting from. Despite this little bit of a rough patch, it serves a purpose in terms of keeping track of everything in one spot. It's not for everyone, naturally, but in time, I believe it can be even more functional overall.
