SVN v1.5 has completely revamped how they do merging -- it is supposed
to be much mo' betta (although I have not tried it myself). The whole
business of needing to track what you have already merged on a long-
lived branch has been eliminated; in this way, SVN v1.5 will be much
more like git/hg/bzr.
However, a key difference over SVN will still be that git/hg/bzr are
*distributed* VCS's, where SVN is still *centralized*. Several of us
have been using distributed workarounds to SVN for a while (e.g.,
using git, hg, or svk as a gateway to the centralized SVN server);
having a true distributed VCS could be quite nice. There are other
advantages, too, such as publishing arbitrary temporary or research
branches (perhaps even on your own server; you don't need to sign the
OMPI 3rd party contrib agreement to get commit access to our server)
that aren't ready for prime-time, etc.
