Having previously owned two WG Chono's and two PG Dato's (silver dial and black dial) I would have to say the Dato. I prefer the crown size, love the large date (so Lange), really like romans, prefer the overall dial layout, and at least to me, it seems to have a smoother wind. I could, however, easily pass on the luminous hands. I also really like the feel of a Plt. watch. I've just purchased a Plt. Dato, so I guess one could say I've put my money where my mouth is.
