I tried ZenHub back before GitHub had Projects, but I thought that Projects had feature parity with ZenHub. What’s the advantage of using ZenHub at this point?
We used it as a layer for rough point / estimation tracking. Not sure that's needed though TBH, in another iteration we had just put estimates as labels and that worked well. I really don't care for burn-down charts and the like, but it's useful to see easily sum up how many points you have in a sprint. I always wondered why github didn't add this one feature... but at the same time I think it's such a better tool than Jira because it's so much simpler.
