Are we talking "better" for Unix/Linux old-guard purist-reactionaries? Or for people who want a server that just works?
I personally just stick to Ubuntu because, on most of the software I download, there are usually explicit setup instructions for Ubuntu, and then "other Linux". Life is too short. Ubuntu is the path of least resistance and let's be honest, it works.
By the way, while I'm not sure about this trademark thing, I personally want Canonical to be a profitable and stable company that can continue to invest, and that will be around for a long time. We can't leave all the Linux money to Redhat.
But for some reason your suggestion really rubbed me the wrong way. Probably because I use Ubuntu a lot and find tremendous value in it. I'll have to revisit my opinions on the matter.
