I use Jupytext since years. It allows me to have three types of synced notebook versions: 1) .ipynb (for opening/running), 2) .md (formatted code+comments, without outputs) and 3) *.py (python formatted, code+comments). I commit the Markdown-version, but I also use the py-version of notebooks for chained notebook imports. Allows me to split larger notebooks into multiple smaller ones. Both of these options are a blessing and Jupytext works super-robust. Finally, when I want to archive (and share) notebooks _with_ outputs once in a while, I have a cell at the end to convert (nbconvert) to HTML, and I commit this html file. The Markdown-version remains as a clean basis for commit history. The HTML file is much better suited for sharing and archiving than the ipynb file.
