Yes, well, I am not saying you are completely wrong, but I do know that you are forgetting about the many people that are teetering on the edge. They are willing to invest some time to save the $$$ MS is charging, but they still need to be able to complete their work. But there is always a break-even point, and a great many people draw that line at having to learn/relearn command line commands just to setup their PC. Does that make these distros better than Gentoo (in many people's mind, yes.) Does that mean Gentoo is a bad distro? Not at all.
As an example, I know several people that I work with started looking at Linux to cut the cost of changing to Vista when XP support ran dry (for personal use, not business), myself included. $400 for an OS that provides nothing but eye-candy and a broken platform to pay people oodles of money for rewrites of their programs, no thanks (okay, it isn't quite like that, but it is what my thinking was at the time). However, I am a VERY knowledgeable Windows worker that uses command line as much as anyone in Windows administrator, yet I still would have had trouble with Gentoo and some of the other more advanced distros when I came back. I am not sure I would have no trouble now, even with what I have learned.
If you really want a distro comparison that features the benefits you point out, you really need to stay looking at the Linux-oriented sites rather than the general population sites. In the end though, the good news regarding Linux is there is pretty much a flavor and entry point for everyone.
