10.1 doesn't have the new menu layout like SLED 10 and you have to setup the Xgl 3D graphical interface yourself (if you want it) howto here
http://en.opensuse.org/Xgl but apart from that they are very similar.
Although all distro's come with Open Office, Novell have tweaked the version distributed with SUSE so that it is more compatible with MS Office files.
UBUNTU craps out for me after installation due to the fact that it ignores the BIOS settings and assumes the drives are in standard physical order.
By the way, select to format the drives with the XFS file format, it's the best. That's something else UBUNTU falls down on, it can't handle the boot drive formatted to XFS.
enjoy..
