My vote goes to the Byzantium model. It's not so common in gen or rep versions, but the rep I got is the closest to gen as I've seen anywhere. I got mine in May.
My only gripe is the datewheel, which is slightly off, being a little off-position toward the centre of the dial, and the font is inaccurate, too. A small issue, but one that I've been attempting to resolve with Jay and Angel for many months, now. I don't have a pic of a gen, but here's the one from the Omega site. I'll attempt a shot of mine, though I'm not so hot with the camera.
BTW: It keeps perfect time ever since it was regulated. It gets compliments all the time.
