While the prequels did have familiar looking ships, they didn't seem quite as identical to the OT counterparts as many of the sequel trilogy ships did, apart from the Slave One of course. Also each movie evolved the look; the cruisers in AOTC for example, evolve into the more OT-looking Venators in the next film. The Jedi and clone fighters do resemble the OT ships a bit but have many key differences. (The Clone's X-wing style ship, for instance, is much larger with multiple pilots).


The TIE fighter is perhaps the worst example-it's pretty much identical, except painted black, apart from the twin-seater variant which has an extra attachment to the wings, some red paint and an antennae popping out. We did get some slight variation with Kylo's TIEs (although his ROS one is pretty much just an interceptor) and the Sith ship seen briefly in ROS, but that's it.

Same with the Starfighters. Apart from a few cosmetic changes (Which largely harkened back to concept art) they were pretty much the same.

Having the Millennium Falcon around of course makes sense but it was kind of weird having them just bring the old Tantive IV back. (an updated version of the design, the Ninka, was Holdo's original ship in TLJ and the model appears several times in ROS's end battle)


The Star Destroyers fared a little better in the first two films-the Resurgent looks just different enough, and the Supremacy and Dreadnought were pretty much the same way. However, ROS decided to get extremely lazy and use the Rogue One/Solo model of the Imperial One destroyer, just scaled up, with some red paint and a ventral cannon.







Even Rogue One seemed to have a bit more variety in it's ship designs with the Death Trooper's TIE fighters, the U-wing, and the variations on the Imperial shuttle (Including "Rogue One" itself).
