I think Suse is better for business educational purposes.. Ubuntu is more focussed on home-office or am I wrong?!
Can't judge on that since I never tried Ubuntu. But with Novel on Suse's back I guess as you said it would attract the business sector since those usually trust the "Big Names" for technical support. Again, just guessing.
I think suse its better for pretty much anything u want to do. home user/bussiness. it really is user friend and for someone that knows little about linux i think suse is one of the best distros you can start with. plus suse its being around for quite sometime now.
I being using suse for 6 years now. and am still a good fan.
