I like them. The Nemesis model seems to have been used for Lower Decks, I wish they'd used it in Picard as well.
It's a little tough to tell. I'd been using the nacelle-pylon phasers as my giveaway, since they're easiest to be sure of from a distance, but on closer inspection it looks like
the stock STO version just added the phasers, but is otherwise based on the FC/INS version. I'd had it in my head STO had FC and NEM skins for the ship as well as the post-NEM version, but I guess I had heard someone talking about applying the FC skin to the post-NEM model (which wouldn't quite be accurate, it'd have that extra reinforcement along the engineering section that wasn't in the movie).
For my own records/future art purposes, I've been splitting them out into FC, NEM, and Post-NEM variants based on the art used on the "trading cards," which, I now realize, just means that the NEM versions are all ones that used 3D renders of the model used on the show, while the FC (
Gilgamesh and
Venture) and Post-NEM (
Valkyrie) ships were using old illustrations of the -E that Eaves had on-hand that were Photoshopped to have different names.
And, checking closer again, it looks like the
Van Citters (and, presumably, the
Wayfairer) have the opposite situation to the PIC
Sovereigns; it was the NEM mods
except the extra phasers, but the fairings and the aft torpedo tubes are there. If anyone cares, the Prodigy
Sovereign is (more or less) the Digital Muse model built for, but not used in, INS, that was on various book covers, SotL images, and Eaglemoss illustrations.
