I've done a lot of experimenting with different bikes and how geometry affects ride and I've come to consider BB height as more important than BB drop because tires have such a huge impact. For example, the 26" Surly LHT is a touring bike and has a "lower" BB or "higher" BB drop than most 26" bikes. However, Surly designed that bike for tires in the mid-30mm range so if you put 50mm tires on it, which many people do, it no longer has a low BB.

In your case, a 700c x 35mm tire has a diameter of about 700mm and a radius of 350mm.

BB height = Radius - BB drop

350 - 65 = BB height of 28.5cm. That's a pretty high BB

350 - 77 = BB height of 27.3cm. That's a pretty low BB and based on what I've read, it's pretty standard for old school road riders. If you expect to ride in rough terrain, 27.3 cm may be too low.

I think you would feel a considerable difference between the two bikes but which is better is a matter of personal preference. If at all possible, test ride each bike or if you can't find a Marrakesh to test ride, find a 700c Surly Long Haul Trucker. The LHT has about as low a BB as anything out there and is very similar in design theory to the Marrakesh.
