Define "good" :)

If you need to have a desktop app quickly (for multiple platforms, even) and it's the difference between launching something or not, then yes it is good.

If memory footprint and performance is a critical part of what you're doing (it's not always), then maybe you should look at a different technology.

I think Electron has allowed a lot of cool things to come into existence that wouldn't have if not for Electron.
