Stefan, I agree with everything you said! For me, the fact that you have a full computer algebra system (in the form of Calc) *and* Lisp behind the scenes in org makes org tables incredibly more powerful than any spreadsheet calculator I have ever seen or used.
The only issue is the possibly steep learning curve imposed by Calc for use within tables (as opposed to interactively via the RPN calculator display). -- : Eric S Fraga via Emacs 28.0.50, Org release_9.4.3-152-g713b3b
