Maybe I'm biased but my favourite is my 1680 red Submariner. Apologies for the poor photo. It has genuine dial, hands,crystal, 1570 movement, crown and bracelet inside a modified yuki case.
I had to sand down the edges of both my genuine and replica 580 end pieces to get them to fit on my Yuki 1680 case. So I guess it may be a common problem. It looks great now though.
