I think kong[1] is better than both options although cobra is by far the most popular. Might be worth a look.

Definitely won't look as pretty as the parent project though but I prefer kong in terms of the actual code you need to write.

OP said they want completion support, which Kong doesn't include. https://github.com/jotaen/kong-completion exists, but the last commit was 2 years ago.
