So, startup-speeds are the same (at 1 second, after my tests), but the one advantage of the Store app over the normal program appears to be program size! Store app only claims 212 MB storage (I just checked after purchasing) while the normal program claims over 100 MB more, at 340 MB! ๐ฅณ awesome!!! So Microsoft Store apps seem to make some sense, after all. ๐ (apart from the very broken app-updater-logic in the entire Microsoft Store)
