As others posted above, low BB is better for touring almost always; more stable, easier to put a foot down, etc. But we need to keep perspective. A lot goes into a bike. BB drop is one small factor. Small enough that unless you are racing fix gears, rarely anything close to a deciding factor.

I have owned (and still tend to choose) a few high BB bikes. Several had superb handling. (I don't like pedal strike In my racing days, I used the very high BB on my racing bike, a full 11", to advantage all the time, pedaling deeper into and sooner out of corners.)

If you are set on choosing between the Aurora Elite and Marrakesh, you could use the BB drop as a tie-breaker but make sure you actually have a tie. Don't pick the bike that will not suit you as well because it has a lower BB. (I haven't looked at either bike. I'm talking about the importance of BB height and don't want to sway my argument with opinions on the two bikes.)
