different strokes for different folks. I don't mind cross platform, but I find Electron unacceptable in any year as a massive step backwards in UI and usability. (Not that you mentioned any Electron-based competitors by name, but a lot of cross-platform big-name competition in the text editor space does use Electron, like VS Code, Atom, and Brackets.)
The competition they have to beat is VSCode and JetBrains - nothing else compares. Yes, VSCode is based on Electron but it shows that it can work well. That's the competition they have to beat. If I can't use an IDE because it's locked to a proprietary OS that requires me to buy specialty hardware to run it then it loses by default.
To echo what GP said, different strokes for different folks. For me I love that it's Mac native (whereas VSCode and JetBrains aren't, and it shows). I use nothing but Macs, and that isn't changing any time soon. Nothing but great for me.
