It isn't the packaging tools that make Debian and the BSDs more consistent in package installation. If anything, RPM has more advanced features than either debs or ports. The Debian and various ports repositories have standard practices for naming, versioning, dependencies, and integration that are adhered to year after year. It is concern for the long term integrity of these package repositories AS A WHOLE that make them easy to deal with. But bullet point differences between Deb and RPM? Not so much.
Debian based distros also tend to limit themselves in how they diverge from the Debian Mothership and periodically resync in any case. I routinely port source packages between Ubuntu and Debian all the time. Since the naming and dependency maps don't diverge much, I mostly succeed at doing this. On the other hand, a SUSE SRPM isn't likely to port easily to Fedora absent a lot of low level surgery on the package metadata. Each RPM distro tends to be an island universe. Deb based distros all have Debian for a parent or grandparent hence the high compatibility at the source level.
For that matter RHEL and spinoffs like Centos and Scientific mostly achieve this as well though the experience is mostly like using Debian Stable without the option of (easily) backporting SRPMS from newer distros.
