The first one looks to me not as a live photo, but as a promo render, albeit a factory rep.
In the second, I am not attracted to the blue color and the standard DW from ST2555.
Third looks gray like titanium, but in this class of reps, most likely it will be some kind of coating that sometimes looks cute, and many people like it, but for my taste it makes the appearance cheaper.
The fourth, in spite of the attractive texture of the tsietblat, seems to be the most unsuccessful in terms of quality; crown, bezel markers, pearl, CG, again standard DW is worse than the rest.
The latter looks like the current XC or V7, which are getting better and better every year (pay attention, they even began to make their own DWs, which until recently was not available on REPS of this level), and at the same time, judging by its appearance, it is steel, and the patinated lumé did not make any PANERAI model worse. I'm sure the difference in the color of the pearl and the marks will be obvious, but of all the evils, I would choose this.
However, this one is just my taste.
