I must admit i liked mercurial a lot. The simplicity that is underrated (of svn) is found in tons in mercurial. In fact dvcs initially was hard to get my head around conceptually with git. Keep in mind the unlearn part is harder from years of svn. Then i actually read a tutorial on Joel Spolksky's website about mercurial and how FogCreek uses it. That really helped me conceptually with dvcs.
