I use Sublime Text with orgextended plugin* for orgmode. I just use it just for the markdown/text editing and labels (:DONE, :TODO, ...) part, not any "advanced" orgmode stuff such as calendar. A colleague uses the markdown plugin for the .md files with ST in the same spirit. I just prefer orgmode. In the end, the main thing is to have colors and hierarchisation of the ideas in one topic. Just to ease the reading of my future self. I have many .org files, one for each topic.
