I use Sketch rather rarely once in maybe few weeks, but i've found out that it quickly becomes uncomfortable to use if you don't renew the license.
I do think Apple could do much better with backwards-compatibility. They don’t need to go Microsoft’s extreme. I thought they’d found a good compromise for years on the Mac, but it’s tipped much too far towards just breaking everything lately.
Once even one person on your team moves to Figma it becomes absurd to use something where you have to share fixed files around and are stuck with only using Macs for your design work.
I still use Sketch for things that only I work on outside of work because I’ve already paid for it but having living documents and being able to share with the rest of the company without them installing software is essential now. Not to mention being able to use my powerful PC workstation not just my Mac laptop is great too.
