It depends on the context really. Sketch is still pretty common in iOS/macOS dev land, and I've seen it used pretty frequently in more "artistic" or experimental stuff, especially hybrid printed/web design projects. Its SVG exporter is also more capable than the one available in Figma.

It's also capable of pasting vector data from Adobe Illustrator, which makes it quite useful when pipelining web assets if you're dealing with vector art done by your art/design dept. or external artists.

It's clearly become a niche product, but it's still extremely useful for what it is.
