We've been in the process of transferring our entire design kit into Figma from Sketch and Abstract since early this year and we're on pace to wrap up in just a couple of weeks! 

It's been a blast using and learning Figma over these last few months.  It reminds me of when the industry made the shift to using Sketch instead of Photoshop many years ago. The tool just feels so empowering. I love it.
