After considering both entries, it is time for the first (and apparently most important) vote. :V
Let me begin by saying that JT deserves respect for his entry, having done his best with the materials onhand. The size of the Gwahaha was appreciable and he did manage to consume the entire thing, and he maintained the core concepts that made the original a success. Furthermore, he earned additional points for presentation by lending the sandwich itself a personality.
Sadly, it is impossible to ignore the crippling downside, which is that the Gwahaha simply did not taste good, which is pretty much the whole point.
HakureiSM, on the other hand, produced a Gwahaha that was not only delicious, but carefully planned and crafted with high-quality ingredients. The sandwich was also quite presentable, with its many contrasting strata laid out in a clean fashion.
However, I do feel the need to point out the relative size of his Gwahaha, despite it's vertical height, appeared significantly smaller in girth. Furthermore, the most important ingredient in not only the Gwahaha but any sandwich, the bacon, was mishandled and did not make it into the final product; a considerable grievance!
Regardless, I feel the best manner in which to judge each sammich is to decide which I would personally prefer to eat, and to that end I cast my vote for HakureiSM as the winner.
