For me, I find I need both JupyterLab and the VSCode Jupyter extension. The vscode extension is superior for step-by-step debugging especially with integrated REPL console. However, I notice running cells in vscode is several magnitudes slower than executing the same cells in a JupyterLab session. Also I use several JupyterLab extensions such as citation manager, mathjax 3, etc and custom kernels utilising docker/GPUs etc. I'm not sure how to use these in vscode and also I'm not a fan of vscode's use of Katex over mathjax 3.
