Nice collection.

SKX vs Mako? I've had both 4 times each and would say that the Mako is more refined.

The Mako in my experience has a more accurate movement out the box, better crown feedback, better alignment of hands, nicer dial finish, dresses up better. Seems that the only risk is that the bezel may be tight.

The SKX in my experience has much better lume, looks better over all and is a classic design, will look better when beat up a bit, certified diver's watch. But out of the 4 I've had the alignment has been off on the hands and chapter ring.
