Apt was designed to be package format independent from the start, it just 
took a while before rpm-support was added. And yes, certain amount of 
debianisms exist in there but separate install/configure stages have 
preciously little to do with anything, apt-rpm simply doesn't have a 
"configure" stage.

For basic updating and installing packages it's pretty much irrelevant
whether you use apt, up2date, yum, red-carpet or whatever, they all
get the job done. Apt has some nice things for developers, like installing
build dependencies of a given package, retrieve and install + optionally
build src.rpm's. It also has an embedded scripting language which allows 
all sorts of cool things like adding new commands and customizing apt 
behavior without having to touch apt's code at all - for example of this 
check out the mirror-selector system in fedora.us apt. In short - it does 
some things that the other depsolvers don't (currently) and lots of people 
happen to like those features :)
