If you are unsure, I would recommend skipping it altogether, seriously.
That being said, I wear a Panerai way more than any other watch and have owned most every Rolex sport model made. But if you have doubts, just move on to another brand.
The Santos is a very cool watch, I have tried it on and loved it on the wrist, which is strange since I am not a fan usually of that case design.
Get the one that really talks to you, if you are buying for investment or resale only, stick with Rolex. Best of luck, the 88 is one of my favorite models, I owned one and will own another again.
