Baseships are better. If you retroseries build you can build them pretty fast. And the extra shield and massive weapons make up for the lack of speed and 40% greater to hit penalty. You need 2-3 dreadnoughts just to get past a baseship's shields. Whereas one baseships can wipeout 1.5 dreadnoughts in a turn.
