Native and Electron apps have two advantages over web though. Fist one is, that they do have access to the file system. This makes a whole range of applications (like Git Kraken) possible. The other is that an application has an icon in the taskbar/dock. When somebody pings me on slack I know where to go to read it. When somebody calls me in hangouts, I have to go fishing for the tab or window with the site open.
