This comes across as a very biased piece. In the "Matchups" that they do. Distributions are scored are arbitrary metrics with no real meaning or valuation behind them. I skimmed down to the Fedora section to see it lost because PackageKit isn't as good as other package managers. I know Mint is the new Ubuntu, but you could at least get a schedule of criteria and then rate everything on how it preforms across those criteria. As it stands this is just how some guy feels about a half dozen distributions.
I don't think I'll go back to other linux distributions after having used Elementary OS Luna. Still in beta so it doesn't work quite right just yet, but the design is absolutely stunning.
