I like the Jedi starfighter designs, but again, why did there have to be a new one in ROTS? It’s sort of indicative of the general problem of the PT designs. More does not equal better.
I liked the one from ROTS, it incorporated some TIE fighter designs (window and interior cockpit) which was cool to see.
The subtle progression towards OT-era tech was cool to see in ROTS.
