Of all the professional Rolex models on the market today, the Submariner Date and Cosmograph Daytona get the most attention due to a combination of factors. They have many similarities even though they offer different functionalities and appeal to different demographics. I have placed the very popular stainless steel Submariner Date (Reference # 116610LN) next to the white gold Cosmograph Daytona (Reference # 116509) for comparison based on size, functionality and aesthetic.

Both of these wristwatch models feature a 40 millimeter case, but as shown in the above photo, the case of the Daytona (12.2 millimeters) is slightly thinner than that of the Submariner Date (13 millimeters). You can also tell by looking at the photos that the white gold Daytona has a yellowish tint as compared to the cooler tone of the stainless steel Sub. The other obvious difference between the models is the bezel, the Submariner with a ceramic bezel and the white gold Daytona with a smooth bezel with the tachymetric scale printed on it.

In terms of aesthetic, each of these models checks different boxes. The Submariner Date is first and foremost a diver's watch. However, it is also a favorite of those looking for a solid stainless steel watch that doesn't call too much attention to the wrist. It is likely the Rolex model chosen most for daily wear, though those numbers are not verifiable. The Daytona, on the other hand, is more of a showpiece. Its busy yet appealing dial and pushers flanking the winding crown give it design details that make it stand out more as compared to other models.

Both of these Rolex models make excellent choices, each with their own unique legacy and admirers. There is a stainless steel Daytona configuration available (Reference # 116500LN) that features a ceramic bezel similar to that of the Submariner Date, however it is the current 'it' watch of the collection, so it is much more difficult to come by than the Sub.
