I see all your CR-90 has a Death Star like laser at PS 12 but then I look at your ship, while my Raider has Captain Needa on it and aimed at yours and think:

1. Imperial Assault Carrier

2. GR-75 Rebel Transport

3. C-ROC Cruiser

4. Imperial Raider

5. Tantive IV

It all comes down to bang for your buck. The IAC's low cost and TIE deployment abilities make it the stand out Epic ship, the GR-75 is an unsurpassed support ship. C-ROC has a couple of nice tricks but lags behind the other two transports, and the Raider and Tantive IV are prohibitively expensive in even their most bare-bones builds.
