You say that you found the solution to the CUPS authorization prompt on an Ubuntu forum, ergo the problem is not unique to SL and can occur in other distributions (e.g. Ubuntu). So why single out SL, then?
If you look in the forums of any Linux distribution you'll find many, many technical queries. The similarities between distributions are more than the differences. So you'll find all distros have umpteen posts about problems with e.g. wireless networking, ALSA, PulseAudio, CUPS. video drivers (nVidia amd ATI closed-source and open-source), X.Org, configuring the system clock (your query in another thread in the SL forum is common on other distributions too), etc. etc.
I'm not interested in starting a spitting contest but, just to show that experiences can vary, I ditched Ununtu and moved to SL because my experience with SL is better than with Ubuntu. For example my wireless works out of the box with SL but didn't when I gave Ubuntu and Mandriva another try a few months ago.
No distribution is perfect, and a lot depends on what hardware you have and how much Linux experience and familiarity you have. Three years ago my stock solution to a video problem was to re-install the OS (Ubuntu, SL, PCLinuxOS or whatever), whereas these days I know enough to fix (usually) the problem.
So it depends on many factors. There are people who have a good ride with SL, and there are people who have a bad ride with SL. The same applies for Ubuntu, openSUSE, Mandriva, Fedora and any other distribution you care to mention. Google "X sucks" (where X = Ubuntu, openSUSE, Mandriva, Fedora, etc.) and you'll find plenty of sites. Google "X rocks" and you'll find plenty of sites too. No distribution is perfect; they all have strengths and weaknesses.
Of the problems that I have for which I do not know the answer, Google usually finds a solution for me, and the vast majority of those solutions are from Web sites for other distributions, i.e. many of the problems are common across all platforms, sometimes worse and sometimes better on other distros.
Some people make the mistake of labelling the unfamiliar as inferior, or blame the tool when in fact they do not know how to use it properly. The same argument also applies to package managers: see for example the thread No simple package manager [Solved]
