I have been using Linux since 1993. I installed the first version of Slackware on a 16MB 386sx-25. Since then I have been using it almost exclusively on one or more of my PCs. So I consider myself as a bit of an expert. I have been using computers since 1982 mostly PCs, but also VAX mainframes and SPARC systems. Operating systems (and GUIs) I have been using include CP/M, DOS, Windows from Version 2 to XP, Geos, Beos, SCO Unix, Solaris, OS/2 and quite a few Linux Distros.
From my experience with Fedora 2, Suse 9.1 and Mandrake 10, Mandrake 10 is the most responsive of all the three systems. It has better package management, fewer bugs and it is by far more stable.
The only advantage that Suse offers over Mandrake is an aesthetic one, in that their OpenOffice icons are prettier than Mandrake's, but I am sure that Mandrake will see to this for the next edition. Yast also looks better than Mandrake's Control Center,although I much prefer the functionality of the later. Particularly, DrakTermServ for settiing up terminal servers and DrakSec have no real equivalents under Suse. The Kolab installation tools is also very cool. Many people don't add the server wizards, which you can do by doing a simple "urpmi drakwizard"
The new two-stage development process seems to be working nicely for Mandrake.
One final thing. All of the Linux distributions are improving and I am glad we have choices. I don't see a need to belittle anyone's efforts and I say this because I think Linux users need to unite more if they expect to displace proprietary software in favor of more robust software that you actually have a chance to share, review and control.
So if Suse is your ultimate distribution, more power to you. I am currently using it at work and i can live with it.If Debian tickles your pickle, great!
But do try new distributions from time to time for more than just a few hours.
