How much do you plan to wear it? Do you want something worth $4-6k on your wrist most of the time, liable to be damaged, lost, or stolen? Would the stress of keeping it safe overpower the satisfaction that it's an original? The great thing about good reps is they can be built to the same ruggedness and durability as gen, and can be worn hard, as intended, without the feeling that you're tearing up a piece of history.
On the other hand, if you intend it more as a family heirloom to pass on to your son, then nothing beats the real thing. I think it's hard to perceive something as valuable and meaningful when it might also be considered "fake" to many people.
I love the really early Tudor subs, 7922, 7923, 7924, 7928, so my decision here would obviously be to build a rep, as gen-like as possible.
