I don't care what Seven did. It's pretty hard to swallow how well the Intrepid-class Voyager stood up - damn-near impossible to swallow, really.
Granted, it was hard to swallow standing up to Cubes, Tactical Cubes and Spheres. But the scout ship was believable. Year of Hell made less sense. For a year she was pounded by an enemy who's torpedoes could walk right through her shields.
Yes the chronoton torpedoes should have had exactly the same effect as the transphasics: bang!
Incorrect.
What I got from YOH was that the Chroniton torpedoes may have had the ability to go through Voyager's shields, but they were relatively weak on delivery (and the transphasic torpedoes essentially explode from inside the ship and carry a far more impressive firepower in contrast to regular photon torpedoes because they are designed to destroy Borg ships).
Besides, most SF ships can absorb several direct torpedo hits, and during YOH, Voyager was hit only a few times (if that much) during each encounter (and we also don't know how many were there exactly - plus Krenim ships were easy to kill off with a sustained phaser hit to their torpedo tubes).
Furthermore, I can recall only one instance when Voyager stood up to larger Borg ships ... and that was in Unimatrix 0.
It was a bit far fetched for the ship to survive as long in a firefight with a tactical cube, but Voyager never did any real harm to it and 7 was on board doing who knows what (you'd be surprised just how versatile and adaptable SF tech is).
Second attack was aided by a resistance Borg sphere which put the tactical cube at a disarray a bit (nothing serious, but the queen ordered self destruct anyway).
When Voyager fought against a sphere ... I recall 2 instances.
One with the future drone that enhanced the shields and phasers (although I found the Borg adapting THAT fast to THOSE kinds of modifications to be unrealistic).
Second instance against a sphere involved Icheb.
The Sphere captured Voyager in a tractor beam and the only reason they escaped was because they beamed a torpedo inside it's shield perimeter and did moderate damage to it (enough to get away).
When it was fighting a Borg cube, well, that particular Borg ship was occupied with 5 children who were out of their maturation chambers too early.
The situations which Voyager found itself in virtually resulted in the ship barely getting away in one piece from the Borg (with exception of Unimatrix 0 and Dark Frontier chase scene with the Delta Flyer).
