I had compared a couple of coreutils with their BSD counterparts for a personal project. Anecdotally, the BSD versions had much more readable code and less compiler/preprocessor black magic. Which also makes them easier to build with non-GNU toolchains (perhaps not out-of-the-box, but with less effort anyway). So, overall they would seem a better match for learning/diy purposes. Poor choice of name though. Debian has a bsdutils package since forever [1]. [1] https://packages.debian.org/sid/bsdutils https://packages.debian.org/sid/bsdutils
