I'm looking at https://www.zenhub.com/product, and while it does have some extra features (filters on priority, labels), but for most people the base set provided by github is gonna be sufficient.

Sure, it won't completely replace them, but GitHub building this as a platform counts as competition.

Using ZenHub also provides additional features like time estimation, burndown charts and Epics (for issue hierarchy) - we find that for larger teams, these are must-have features to work inside GitHub.
