I haven't tried CVS branches but in svn I frequently had problems bringing 
a branch up to date with respect with another one. What happened is I end 
up with cases in which svn didn't properly delete the files that were 
removed so I had to do a lot of grepping and svn rm/add to take care of 
it.

I'm not sure I understand why is this harder. One thing I forgot to 
mention that I really like is the fact that merging will preserve the 
original commit log so you can really see how something happen.

After using svn and git I find awkward the per-file way of working of cvs. 
It's really much easier to think in terms of revision number of a tree. It 
is true that about half of the commits (49% or 530 out of 1068) are one 
file but most of the changes (92% or 6520 out of 7050) are part of commits 
that touched more than one file. The percentage is still high even for 
changes that touch more than 5 files (77% or 6080 out of 7050).
