I got the 4Sevens 18650 tube for my Quark collection. I plan to use it on my AA^2 light. Which option would yield the longest runtime in a Quark AA^2? Two Sanyo 2700's or one AW 18650 2600mAh?

Although the voltage determines where a light drops out of regulation, when all else is equal, the power contained in the batteries is a reasonable indicator of which cell(s) will go longer. The choices you suggest are AA = (1.2 x 2) x 2.7 AH vs. Li = 3.7 x 2.6 AH. The AAs = 6.5W vs. Li = 9.6W. I'm assuming the Sanyo's are NiMH and not alkalines, but even using alkaline's 1.5V per cell, still gives the edge to the 18650. The 18650 should outperform the pair of AAs.
