I wrote marcel. In my view, nushell and marcel are very similar. nushell has tabular output, which I haven't thought was all that useful.
Marcel is python-based. The nushell guys have had to invent a lot of language. By basing marcel on python, I don't have to invent language. Any logic to be added is expressed in python. E.g, do a recursive listing of files and find those that changed in the last 3 days:
ls -fr | select (f: now() - f.mtime() <= days(3))
The stuff inside the parens is a python function, applied to a File f, piped in from ls. (Marcel lets you omit "lambda".)
