difference between synaptic in pclinuxos and ubuntu

[opiumpoetry]

I've noticed that when I uninstall software using Synaptic in PCLinuxOS, I never have to remove residual config files afterwards, whereas when I used Ubuntu and Ubuntu derivatives I often had to do so after removing software. Just out of curiosity, what accounts for this pleasant discrepancy in PCLinuxOS versus Ubuntu?

Synaptic is a computer program which is a GTK+ graphical user interface front-end to the Advanced Packaging Tool for the Debian package management system. Synaptic is usually used on systems based on deb packages but can also be used on systems based on RPM packages. It can be used to install, remove and upgrade software packages and to add repositories.

PCLinuxOS uses apt4rpm as package manager.

Synaptic development was funded by Conectiva, which asked Alfredo Kojima, then an employee, to write a graphical frontend for APT, continuing the work initiated with the creation of the APT RPM backend, apt-rpm.

Other difference between PCLinuxOS and others: PCLOS uses 1 repository (megagames can be added) and others uses multiple repositories.

I guess either apt4rpm is better than apt or maybe synaptic just works better with it than with apt.
