Both are important, so can't say that one would be better than the other.

I don't know of any hard data, but Kirk Anderson's studies suggest fresh.

Again, no hard data. Would depend greatly upon the fresh value of each.
But in general, long-aged beebread is discarded by the bees.

From my own trials, they consume fresh incoming pollen preferentially, and
ignore pollen sub during a good pollen flow. But they EAGERLY consume a
good sub if there is any shortage of incoming pollen.
