Oh boy, one day we should probably have the Great Borg Queen Debate - it would be a thread for the ages...
we’ve progressed over time to wanting more hard and serious technobabble.
That's the thing, I think the technobabble surrounding Su'Kal is actually pretty good. I will grant that the episode has a lot going on, and it's easy to miss, but it's solid enough that it's had me doing some light genetics research on more than one occasion.
