Now Voyager takes on a Borg Tactical cube, you know, a borg cube amped up to the inth degree. And single handedly cripples the cube.
I'm afraid you are mis-remembering "Unimatrix Zero." In "Part I," Voyager
gets her ass handed to her by Tactical Cube 138
and only survives by warping away -- which was fine, since the plan was to take some damage and then warp out as a distraction for the team from the Delta Flyer
beaming aboard. But they certainly didn't win that battle. In "Part II," Voyager
fares a little better against 138
, as she's aided by a Borg sphere that's been hijacked by liberated drones from Unimatrix Zero, but she still only survives because the Borg Queen initiates a self-destruct sequence for Tactical Cube 138
as an attempt to kill Janeway while she's aboard.
Buzzer -- the guy from the 20th century said that the Enterprise wasn't as efficient run as a luxury cruise ship he was once aboard.
To be even more specific, Mister Offenhouse compares the Enterprise
-D unfavorably to the RMS Queen Elizabeth 2
, which was an ocean liner rather than a cruise liner. (Ocean liners are built tougher to withstand constant travel on high seas running regular trans-oceanic routes; cruise ships aren't as tough, and are built for shallower and less harrowing waters, for cruises rather than regular trans-oceanic routes. Think the difference between a pick-up truck and a luxury car.)
