In Guns, Germs, and Steel, Diamond says it is better to live on an east-west axis. Are there any benefits to living on a north-south axis?the...

As you know, the bad part of living in a place with a long
north-south axis is that crops (even if they are diverse) cannot diffuse along that
axis.  So when a society north or south of you domesticates a crop, you can't
necessarily copy them.  That makes it harder for you (and those other societies) to
develop.  In that case, you should try to think of what benefits there might have been
to living in an area where crops couldn't diffuse.

I would
argue that a major benefit would be that you are less likely to have your society
overrun and conquered by other societies.  If you live on a long east-west axis, a
society to your east could come, conquer you, and take your lands because they would
know how to farm in an area like yours.  If you live on a north-south axis, other
societies would be less able to conquer you because they would have to adapt to a whole
new way of life in order to take your lands.
