01 vs Corrupted for XP

As the title states, difficulty aside, which gives more XP per level, a box of parts, or a corrupted archive.  Also by how much more does one give over the other (approximations are okay.  "Double; gives 1/3rd of the other; etc are valid answers).

I'm pretty sure it's the same base # of XP, but a corrupted archive gives double a box of parts because it's 40 DC, not 20 parts.

The answer is Sleep Walker boxes!

Lawl, it's Pandora Boxes!
