I don't entirely understand the issue. So you've been using, (and I'll assume, liking) SuSE Linux, and you find out it's actually based on Debian Linux, so you want to switch?
Does knowing a bit more about the system you've been using change its functionality? What's wrong with Debian? If I wasn't using Gentoo now I'd probably be using Debian or something Debian based (like Ubuntu, which I really enjoyed)...
Now that you know it's based on Debian Linux, why not try taking advantage of that? Learn how to use APT...it's an excellent package management system and it will only make Linux life better and less stressful

.
All of your issues with Debian (and Debian-based) are non-issues. Debian doesn't need a "fixed package" at all, though it offers a very robust package management system if you should want it. Anything, if you have a compiler, which you should, will accept regular tarballs. Nothing 'requires' a specialized type of package...
No distro prevents you from upgrading your kernel should you want the latest alpha-warning--under-development-crazy-unstable-bleedingedge-onlyfortesting-whatnot vanilla Linux kernel.
As horndude says, Linux is Linux...(is Linux...)
