Ok, that makes it "the simplest way for most users, especially if you
are not an expert", as DapperUpgrades states. But does it do anything
else that needs special manual intervention (above that mentioned on
DapperUpgrades)?

"more sophisticated, special-purpose algorithms ... and we fine-tune
them to ensure that the upgrade does the right thing" sounds like
something an expert user can achieve just as well with this equipment:
DapperUpgrades, aptitude dist-upgrade, some knowledge about the package
manager, diff, conffiles and text mode editors; common sense; dpkg
--force-things

I'm still interested in whether an upgrade via update-manager results in
an in any way different upgraded configuration than applying the tools
mentioned above. Or in other words, is it advisable even for experts, to
use update-manager instead of CLI (aside from the time savings), even if
they strongly prefer CLI, and why, if so?

Thanks,
Mario
