The development of apt-rpm is stalled, afaict, and urpmi's dependency solver is superior to the one of apt (-rpm or not) (being able to solve a wider range of problems.) However apt-rpm is available for mandrakelinux for the weird people who really really want to use it. urpmi is not going to disappear soon. (Moreover it's written in Perl, so it's obviously superior:)
However the author of apt-rpm is working on a new package manager, smart, which looks very promising, but which is still alpha.

Not forgetting to mention other handy tools -- cpufreq, klaptop, etc.
