First Rolex - OP 36 or Sub?

[Trystero]

I'm finally in a position to purchase my first Rolex and I'm having a hard time picking between the 36 mm Oyster Perpetual and the no-date Sub. I love both for different reasons (the OP's simplicity and the Sub's classic look), but I suppose the choice really comes down to whether the Sub is worth the extra 2K over the OP. If anyone owns either of these watches I'd love to hear your thoughts on using it as a daily timepiece. Thanks!
