Hard to choose because they're so different, so why not both?
I have a 5146G and steel Daytona and like both. Not sure about a Daytona on a rubber strap, so I'm leaning towards the 5146G. Can you get the white gold, blue dial? That's a beautiful Daytona.
Also since you mention you have large wrists, make sure you try the 5146G first, I would describe it as a small watch compared to a Rolex.
