Arch PKGBUILD packaging is basically identical in design to RPM packaging, and can contain more than just s single build script (patches, pre/post scriplets in another file, etc.). Arch packaging feels familiar and "normal" if you're coming from any RPM based distro, including the SUSE family.

It is the DEB format which is generally unlike most others in architecture and design, you cannot toss "Fedora/Ubuntu" into the phrase and be honest, they are quite different and have different design goals.
