Design is a team sport, so what you need to ask yourself is does the whole team prefer to use a native mac app vs browser? RIP sketch
My design team and myself will take the sanctity of a native app to create quality work any day versus a "design" free for all in the browser with everyone playing decorator.
I manage a design team and there’s no way in hell we would go back to Sketch.
To even think that having a “native” app has any bearing isn’t accurate at all. Sketch is so slow compared to Figma. You aren’t using multiplayer everyday but when you do need it, there’s nothing like it.
Knowing that they had a monopoly on creative software, they raised the prices to the point of completely locking out a significant portion of their userbase.
If they could, they would do the same to XD.
Seeing you write this, a doubt creeps that you ever used Sketch.
But if your team itself is functioning well and has respect for each others input it works well.
Agree to disagree (without calling it stupid beyond comprehension). Design is so much more than final UI. It's the whole experience, how it works and how it's distributed. And that involves a lot of stakeholders, not just one designer.
