I don't understand your clipboard remark. Ctrl+C and Ctrl+V works everywhere. Emacs by default uses a different copy-yank shortcut system, but that too works perfectly well with the clipboard out of the box since some years ago. In order to have the clip stay alive when the sender closes, your desktop environment has to do something I think, but that too works out of the box in GNOME, I just tested it. If that was your problem, you were perhaps just missing something in your i3 setup? I think it is to be understood that choosing a more fiddly tool means having to be spend more time fiddling with it. A default install of the big distros are not fiddly. In addition to that, you also have the convenient middle-button instant copy-paste thing.
