We abandoned Github issues for Trello and also use it for project management amongst other things.
The single most useful thing is having all items in one place, be they features, administration work, bugs etc. It is trivial to reprioritise and trivial to see what is going to be done and has been done. You can also assign more than one person to a card which is handy sometimes.
The problem with most trackers is that they are project based and you often end up with your backend, frontend, Android & iOS apps being different projects. But often issues and planning span the projects, so you end up with arbitrary information and issues all over the place.
For wikis we've mostly ended up using Google Docs. Having people learn yet another syntax hasn't been helpful, and again you end up with cross project issues and linking.
