After using Hangouts for years now, I've become sick and tired of it, and have finally found an alternative. Unfortunately, this is only for the text/image chat functionality, but it's a very good replacement:

It was on the front page of Hacker News just a couple of days ago, and that's where I found out about it. Much nicer clients, open protocol (so you can even make your own clients), reliable, and many more features than Hangouts make this a much better alternative.
For voice and video, however, I haven't found a good alternative that is easily accessible to people that don't want to set things up on their computer. Hangouts will just randomly not work for me, depending entirely on random chance, and I still can't find anything more convenient than it.
