You really can't go wrong with any of the watches you picked out above.
The last two have cronograph functionality obviously, and use the Omega caliber 1164 movement. The 1164 is a reworked ETA/Valjoux 7750 with an updated bridge, heavier rotor, and rhodium plating. It has 25 jewels that are used to reduce friction at key points in the movement. All 25 jewels are functional IIRC, the movement is well tested and rock solid.
The other (coaxial) watches use the Omega caliber 2500 movement and is a reworked ETA 2892 movement. The 2500 contains two more jewels than the 1164 bringing the total to 27. You could write a book on this movement, as it represents a major advancement in watchmaking.
The caliber 2500 is the more special of the two, IMO. I wouldn't necessarily give up the chronograph functionality solely for this reason however should you prefer or require it.
Both movements meet the chronometer specification outlined by COSC.
P.S. I prefer the black face, but of course it's really your preference that matters, and you should make sure that you are 100% happy with whatever you buy. Good luck.
