I love this thread.
*sigh*
my personal favorite is the firestorm class frigate. upgunned sword that has one hell of a punch for it's class. slap a cloaking device on it or an eldar holofield and you really start to get annoying.
for bigger ships I'd have to go with the lathe class monitor cruiser. archeotech goodness in a pretty hard hitting cruiser that if properly outfitted can stay out in the expanse for a very very long time. bad guys will think twice about attacking you in a ship that big, and you can exploit the hell outta anything you find out there.
