I think you might have some of our names mixed up.First I want to call Zar out on what I would describe as purely epic trolling. Your trolling rages on even in the face of facts and logic in the greatest troll style.
The debate wasn't about whether all the cubes were the same size. There was the assertion that the tactical cubes in VOY were drastically smaller than all previously-seen cubes, thus excusing their apparent weakness. But this is nonsense because their original introduction was clearly meant to tell us they were more dangerous, and they were shown in fleets with the First Contact-type cubes, which devastated Starfleet's whole force, and were clearly the same size.Also the debate about cubes being different sizes, of course they have cubes of different sizes. Borg scout ships are cube shaped and smaller. Borg probes like the one that voyager destroyed were probably the successor to those.
I'm not sure what you mean by "quite a logical drawback". Does this mean "this is quite obviously a drawback" or "the Borg's uncreative nature is illogical"?The nature of the Borg makes them inherently uncreative, they rely on other races to provide them with upgrades to their technology and don't generally research it on their own. This is quite a logical draw back.
I think its quite plausible that the federation gained a significant leap forward on the borg because they're creative and motivated. The Borg on the other hand only get new tech when they assimilate it.
Yes, the Feds' advantage definitely lies in their creativity and ability to think individually, but I don't buy that this means they would overshoot the Borg in technological advancement. The Borg can instantly assimilate any race's technology and integrate it with all the existing technology from every other race they have already assimilated. This would easily give them an edge over any single race's technology.
