Not to say don’t (do try it), but Darcs might be better if you just want to understand some of the fundamentals since it’s more mature. A small project will not perceive any performance difference. If you use Git’s CLI heavily, Pijul’s CLI will seem barren in comparison & tooling even like vim-signify doesn’t have support. Pijul’s diff isn’t GNU diff compatible so that tooling won’t help either.

If you grasp Darcs, moving to Pijul is pretty simple since they are based on the same theory—you just might need to be invested enough to start building your own tooling which is more of a time commitment. Pijul is meant to be scripted which is partly why it’s barren—so for a trivial expample I created a small shell script pijul-amend which wraps pijul record --amend which is picked up as pijul amend mimicking darcs amend. Maintenance is easier when a project supports only the minimum set of commands, but you’ll be building your own ergonomics (no rebase, no send-mail, etc.). Maybe in the future when there is a bigger contrib space to fill in the gaps, it won’t be such an investment to just to test out.
