Two things keep me in Sketch. The main one is its extensibility: I rely on a number of great plug-ins (most notably Runner, but others as well including one or two that I wrote myself). Those don’t exist for Figma and can’t exist until they implement more of an API.

Secondarily, last I checked Figma lacks full offline support. I don’t usually need to work offline, right up until the point when I really really do.

I haven’t played with XD yet and keep meaning to...but I have trouble gathering the enthusiasm to do so given the trajectory Illustrator, Photoshop, and Lightroom have taken the last few years.
