It was an internal app, a GUI to configure a CLI tool in a user friendly manner. For that use case, I essentially built a local SPA with Vue that can also call some endpoints on server side software that we also host. There, the rendering differences between the web views didn't really matter but the small distribution size was a major boon, plus being able to interface with Go code was really pleasant (as is that whole toolchain). No complaints so far, then again, not a use case where polish would matter that much.

I'd say that the biggest hurdle for that sort of thing is just the documentation or examples of how to do things online - because Electron is the one everyone seems to use and has the most collective knowledge out there.
