It's LEGO vs. Mega Bloks, Star Wars vs. Halo, Super Star Destroyer Executor vs. Charon Frigate Forward Unto Dawn. It had to happen! I have both sets, so I threw 'em both on screen to see what would happen.
Of course the "real" ships are of completely different size (62,000 feet vs. 1,600), but these two brick-built models are moderately comparable in mass & number of pieces. With each being its manufacturer's longest starship model to date, a comparison seemed natural, if not mandatory.
