Smaller AP RO doubts: 14790 vs 15450.

[Cezinho]

Hello AP watch lovers,

We all start our watch addition somewhere and mine has been developing quite fast.
I own currently only a Rolex SUb 2 liner 14069 and an Omega Speedmaster that I picture below for wrist reference and would like to enlarge my watch rotation with a different style (considering also a white Daytona but upfront comes the RO).




My wrist is around 17cm which equates to 6.75 inches and therefore my preference goes to smaller watches (say max 40 as my sub above).
I was eying the RO 14790 blue dial , a 36 with JLC caliber , thinner that the new 37 version, which in the condition that I look for ( full set and not polished or minimal ) is between 10 and 12k - never tried this watch and will most probably not have the a chance to try it before buying.

or the new that I tried this weekend 15450 (37 and in house movement and thicker case )in blue dial below:l which has a retail of 17k€.



I know most of you will advise to go for 15202 but I strongly believe would be too big for my taste (see 5711 below that fits smaller than the 15202).

Question:
Which one would you go for ?
Meaning technically , aesthetics's and value (not my most important criteria).
Are there besides the movement other important specs that were changed in these recent versions that I should be aware about ?

Your thoughts please .

Many thanks

Ps wrist shot of r 5711 also for sizing reference.
