Just tried Sketch 3: in some ways it is now even more iOS centric (now has iOS templates out of the box), but the multiple (export) resolution support is a major improvement for Android (previously it just offered 1x, 2x which was completely useless for Android).
I've used Sketch 2 a lot for Android work; it is fantastic and I highly recommend it, though I wish they would give first class support to Android. However, I imagine the developers have to worry about how Apple might react (maybe less likely to get featured etc).
