17 It's mostly the same, except for things that are eligible for
18 removal by emerge --depclean. I advise people to use @world and
19 @system instead of @installed whenever possible since @installed
20 makes it impossible for emerge to solve blockers by automatic
21 uninstallation of blocked packages [1]. I've recently updated the
22 documentation to warn about this undesirable side-effect [2].
