I think both are good seating areas. I personally prefer to be as close as possible, as long as I'm not too far out to the side, but front row mezz is pretty good and gets you a little bit more of a few of what's going on the entire stage. What side are you looking at? Right or left? Because there is some stuff that happens on the left side of the stage (left from the audience's perspective) so you might miss something if you are sitting on the left side of the orchestra. You'd be ok on the right side though.
