Switching from Ubuntu

Planning to switch from Ubuntu. Mageia appears to be more focussed on Linux than Ubuntu.
But here are the questions:
What are the pros of switching? (Latest versions of, say, KDE, etc. appearing before they appear on Ubuntu, Better configuration tools, etc.)
What are the cons? (Availability of packages, deb vs. Mageia's package management tool, etc.)
Initially, I plan have a dual boot system running Kubuntu and Mageia on two separate bootable partitions and a home partition common to both. Is this workable? What could be the problems?
