Frack me that legacy one is right on the money shot!!! - ok my problem i can't see the difference between baz and wiley (OH NO!!! runs for cover)
the only thing i can spot stirght away is the difference in font on the underside of the saucer
but meh ...Cookies away!!
There are a few tells...
-Baz's saucer rim windows are stretched out along the bottom of the saucer on the port and starboard sides
-The rim around Baz's deflector is a bit more rounded right beneath the leading edge of the neck, Wiley's comes to a bit of a peak
-Wiley's has thinner nacelle pylons
-The backlighting on Baz's deflector has a distinctive purplish hue to it
-Wiley's deflector dish has a metal rim just before the leading edge of the drive section like the Season 1,2 model. Baz's deflector ends at the rim a la season 3-7 model.
-Wiley's transition between the engineering hull and the neck is smoother
-The backs of the nacelle grills on Wiley's are beveled into the nacelle body by the same amount as they are all the way around.
There are a lot more. One of the big things you can tell is the difference in the reference material that is used. I know for a fact that Wiley used the renders from a 3d model, while it looks to me that Baz used a version of the Sternback drawings, which incorporated elements of both the season 1,2 and seasons 3-7 models.
