i'm in the market for a new (complete) bike to be used 80% of the time for commuting and long weekend rides w/ rear rack and pannier, and 20% for medium loaded touring w/ two panniers on the rear and a small front rack w/ rando style bag+supplies.

my riding tends to be comprised of 80-90% on pavement (including rough roads), and 10-20% on gravel/dirt/trails.

the two bikes i currently have my eye on are the (2016) Jamis Aurora Elite and Salsa Marrakesh.

besides the gearing, the quality of components look to be fairly similar on the two.
the one thing i'm noticing that differs greatly between the two is the 12mm in BB drop.

Aurora Elite = 65mm BB drop
Marrakesh = 77mm BB drop

i'm wondering what sort of advantage one would have over the other, and what sort of real world difference i could expect to feel on each bike. i've heard that the lower the bottom bracket the more stable the ride is, especially when loaded, but is that enough of a reason to choose a bike with a 77mm drop as opposed to 65mm?
