Both, but sabayon is closer. Paludis doesn't even try to stay compatible, sabayon relies on compatibility to leech off new stuff.
Score: 1:2Yes, both use the Gentoo bugtracker and point their users at Gentoo support channels. But whereas sabayon users can usually be convinced that they are not using Gentoo the paludis-infected entities usually claim that because the paludis homepage claims it is better than portage it can't be buggy. This might be amusing if it weren't bugspamming places that have nothing to do with it with bugs they cannot reproduce.
2:3Yes, both have arrogant leads that have egos the size of Jupiter. But ciaranm wins hands down. As the only person to be removed from his position as Gentoo developer twice he is the undisputed master of spam (dominating the -dev Mailinglist with up to 20% of all emails sent) and making people lose motivation.
4:4Whereas sabayon claims that sqlite is fast and other amusing things this is overshadowed by the bad code, template abuse and lack of documentation in the paludis code base. The sheer misengineering (usually claimed to be "smart" code) of paludis wins this round easily.
5:6The misdirection and propaganda of Sabayon is already quite interesting. #sabayon is full of insults and usually redirects people to #gentoo. #paludis kickbans all that don't agree with their special brand of stupid and orchestrates nice spamfloods on everyone who doesn't appreciate them.

Ever wanted to find all packages using the Beer License? Need to know all packages that depend on this library? There's a great tool for it: pquery
It comes bundled with some other stuff you can freely ignore (like pmerge and pmaint), but these are so small that noone bothered to frickel the ebuilds apart. If you want to get it installed, it hides in the sys-apps/pkgcore ebuild.
So once you've spent the 30 seconds or so it takes to install you can run it as any user that is in the portage group (otherwise strange things may happen). You may wish to not use pmerge for now, while it aspires to be a complete drop-in replacement for emerge it might not work exactly like portage. And then if there's a bug you get twice the work because you'll have to try to reproduce it with portage and all that.
But feel free to do "emerge -p gnome && pmerge -p gnome && time emerge -p gnome && time pmerge -p gnome" to see how fast it goes! Wheeeee!
Anyways, uhm, yeah, pquery.
pquery --attr=license '*' | grep GPL-3That's all of the GPL-3 packages.
pquery --revdep="sys-apps/portage" '*'And that's all things that depend on portage.
pquery --maintainer=welp '*'That's all those where you can tell welp that he is a slacker
pquery --helpAnd that's all the other great options you can play around with. If you have any questions #pkgcore on irc.freenode.net is a good place to start ... and have fun datamining the ebuilds :)
