I agree with you, and I think this is a pretty good signal that Sketch is REALLY feeling the heat from Figma, because they aren't offering a better argument besides "we're native". The bandwagon has clearly jumped off Sketch and onto Figma, and not because it's "fashionable", but because Figma is plain awesome.
Yep. Our company switched to Figma and it's been leaps and bounds better for productivity. Having multiple people working on the same design file at the same time has been huge.
As someone who's worked on a lot of collaborative technology, I find it weird how most of the interest in collaborative editing is confined to the web. As I understand it, Figma's internal collaborative engine is written in C++ anyway.
