I would personally take Benzinger over ML. Yes, it is true that ML 135 is some what of In-house movement, but I don't believe the work that went in justifies the price IMHO.
At least with Benzinger, you can see the amount of work that went into make it so beautiful using rather pedestrian movement beginning as well as the pricing being rather reasonable IMHO. Also, IMHO, it is easier to see because of the non-skeletal outer markings. (Images from Watchbuys.com)
