One important reason people choose to use Electron instead of opening the app in a Browser window, is that the browser blocks a lot of standard keyboard shortcuts. So for example, if you want to capture Ctrl+Tab and move to the next note, based on that, well, you can only do that in Electron. Another UX based reason, is that native menus offer a better UX than having to put buttons for each and every action inside the app. So apart from the usual arguments of cross platform, and we already have JS developers, there are other good reasons to go with Electron. Also, if you want to do something like display a decently advanced HTML view, WKWebkit might or might not cut it. And it get's updated only when the OS itself get's updated (atleast on older versions of OSX). So if that's the kind of thing you want your application to do, then you pretty much have no option other than Electron.
