While I agree it's hard to claim one is outright better than the other and there are a lot of factors that go into it, I do feel it's important to toss my chip in as someone who's not familiar with Lisp, Scheme, or any other functional language that I find it's syntax and layout particularly difficult to parse, let alone get started with compared to say, the INI-inspired systemd conf files. I can detail why but the mere fact that I'd have to learn an entire functional programming language (no matter how "easy/simple" it's claimed to be) to be able to competently edit a service file is a huge immediate turn-off for me.

This is very basic Scheme syntax (plus Guile's keyword argument extension), nothing advanced and definitely not all of Scheme.
