I don't understand why this is even an argument. Yes, obviously the entire point of bringing back armor from the future is that it's a better defense than contemporary shielding. But "better" does not mean "absolutely impossible to defeat."
Again, sure, impressive, but not "God mode" undefeatable. That's my point. It's an edge, but only a temporary edge, like every other weapon you can use against the Borg.
I was actually talking about how the armor was useful against the Borg not whether it was a god mode or not.
Sorry for the confusion.
Of course thinking about it I think the reason in universe that Starfleet would go with armor instead of shields is that the Borg can drain shields where as armor can't be drained by those tractor beam things the Borg use.
