Are you kidding me? There are many reasons to pick a non-electron platform without the need for particularly high performance. Android/iOS are good examples of the reasons why. There's just so much to be had by integrating with the OS and the environment that the user uses your tool in. Electron is great for a prototype or as a way to get your feet wet in improving the desktop experience. The best user experiences will always be founded on the native technologies of the target platform.
