For me, the biggest advantage of VIM is vim-tmux-navigator, which makes navigating between vim splits and tmux panes seamless. Pressing CTRL-{h,j,k,l} navigates to the next split or pane in that direction. I don't think I'll ever be able to switch to a GUI editor unless I can navigate between that editor's splits and my tmux panes in the same way.
