What makes you say, spheres are better. I gather that there are several variations, not just cubes and spheres.
I think they have spare clones of the queen, but only one in control at any given time.
The borg are one of the strongest/most interesting species introduced in the show. But what I don't like is the first time they were seen (in TNG) they were bad dudes. Federation ships got smacked silly. Now in the season premiere/finale episodes, voyager took on some borg tactical ship and beat'em down. What's the deal with this mentality that if the crew is sufficiently determined, they can overpower a borg ship. WTF!
hehe, dunno. i havn't watched that eps yet, but voyager does have 7of9. my understanding of the queen is that she is not really a physical entity.. she just posses a body whenever and where ever it is convenient.
That part about the borgs is true they started to fight them in Next Generation they were even afraid to come near them. (BTW Enterprise is stronger than Voyager + Ships in Delta quadrant are stroger than in the alpha)
