I use all three of JupyterLab, Jupyter Notebooks and VS Code Notebooks.
What I love about VS Code Notebooks - it's almost zero context switching to jump from the the code you are working on to a REPL and back.
What I don't love about VS Code Notebooks (and why I still spend a lot of time in JupyterLab) - the context gets confused as to what cell you are in frequently - so your Ctrl-Enter keys don't work, and you have to manually run each cell one at a time.
~Removed comment about graphs not being inline~ - I stand corrected. Just checked an the latest version does let you show your graphs inline. And they look awesome.
