upgrade will only install newer versions of packages. If package foo
changes its dependencies from bar to barc2a (for a C++ ABI transition, for
example), then upgrade will not attempt to upgrade package foo.
Dist-upgrade is allowed to install new packages and remove old (hopefully
only obsolete) ones. So dist-upgrade will upgrade foo, install barc2a, and

Aptitude and apt-get do indeed handle dependencies differently. Well, they
have a different set of logic to try to resolve dependencies. Sometimes
that leads to different results, sometimes that leads to more pain doing a
specific circular upgrade with one versus the other. People's experiences
and impressions vary wildly.
Hope that helps,
