The minute I heard about VOY I wondered how they'd address the Borg issue.
That being said, the idea that "Scorpion" or "Dark Frontier" were better than BoBW makes me chuckle a bit. I'd be curious to see what they would have done with BoBW if they'd had the FX advances that were available by the time of VOY.
Seven of Nine is the reason "Dark Frontier" is better than "Best of Both Worlds". The show has a real emotional center which I don't really get as much BOBW.
