My own personal experience of Marimo vs JupyterLab is that they're both really useful tools, but with somewhat differing (but overlapping) purposes. Marimo has become my go-to for when I want something "notebook-like" but which operates more like a fully-fledged application than a Jupyter notebook would, where JupyterLab still (at least for me) is the better choice for random explorations, learning, and note-taking/documentation of my learnings. At this point I'm really feeling like it's a good thing to have both handy and available, since neither one is really a complete replacement for the other.
