I for one am okay with the idea of spawning an entire headless browser for something that uses a full window - slack, spotify, etc. but for drawing a toolbar? That's a bit much.
There is plenty of reasons to not like Electron apps, but that they don't look right is not one of them, as Electron apps don't come with any styling built-in, it's all up to the developers of the apps to style things.
Yeah, that’s the problem: I don’t want to use apps written in frameworks that let the developer style the basic controls. If I’m ok a Mac, I want to see Mac buttons, dropdowns, etc. and I want them to be provided by the OS so I can rely on OS services working: the Cocoa input system is pretty sophisticated and I inevitably run into edge cases with attempts to emulate it in electron apps.
To be fair, OP was clearly talking about native apps. My 2c: an Electron app looks "alien" (for lack of a better word) on every platform that supports it. Especially so when it implements deep integration like a menu bar widget. One would expect it to obey the operating system human interface guidelines. This in itself makes it unsuited for the task. Even more so when the main reason to use electron (code reuse and ease of porting to other platforms) is not fully realized (as this appears to be mac-only).
