Ah... My experience differs :-) For example, many keyboard shortcuts don't work over tables (because they conflict with those from the browser; maybe Electron helps here, don't know); copy/pasting images is not easy; editing complex data structures is not easy, especially when you want to transmit delta-edits to the server; it's also tough to freely draw over controls (for example to give visual hints here and there). But well, Qt presentation is not nearly as sexy as HTML/CSS, that's for sure.
