Yes, still using both. I have TONS of legacy files in Sketch for the client so I don't see switching that client over anytime soon. But all new client work is being done in Figma.

I've been using both for about a year now. The nice thing is I can switch pretty seamlessly because the UI is very similar and a lot of keyboard commands are the same. The big difference is in how I share.

With Sketch, I use Craft Sync to push everything to InVision, then share a link.

With Figma, it's just there. The client comes in and sees everything. Feels a little weird at first, but I really haven't had any issues, and what's more, both clients I'm using it with have picked it up and started using it themselves.
