In my studio, live sound, club, and DJ experience over the years, Rane gear is much better built and better sounding than Behringer. Behringer definitely has the feature list to its advantage, and in light-duty home theater use, build quality may not make much difference, but Ranes have tons of headroom, switches and pots that don't get dirty, higher quality capacitors, cleaner signal paths, etc...
Many people have been very happy with Behringer gear over the years, but there are good reasons for the extra money Rane asks for their products.
