I've gone through the same process of evaluating x-platform alternatives and I can now understand why Electron is so popular.
I mean, you do have the unreasonable bundle size, but other than that you can make really good looking applications using the same tools you can use to make web sites for both desktop and mobile.
I've been eyeing https://neutralino.js.org/ since if I'm going to make the app render right on browsers then relying on the same code via webviews likely isn't (much) more portability effort.
