suse verses ubuntu

I have noticed a lot of outfits are using Ubuntu. Dell is offering it.
Anyone know how Ubuntu stacks up against Suse.
Wondering what the major differences are. I am still going to use Suse,
but have been thinking about putting Ubuntu on as a second OS and seeing
how it works. But what to get some input about it first.
