As an end user hand assembling desktop services on non-Systemd distros (Artix, Devuan, Gentoo, Guix) over the years, and thus had no concern about APIs, Pipewire just works and PulseAudio gave endless trouble.
As another user on Gentoo, pipewire is a never ending pain in the ass full of "magic" behavior and weird bugs. I mostly skipped pulse though so it may be simple in comparison to that.
