Leaf-and-Spine Fabrics versus Fabric Extenders

Hi all!

We are using N7k with FEX architecture and sooner or later we're gonna move on to N9k. Our architect team was choosing between classic scheme with fex and Leaf/n/Spine. They choose fex over leaf and spine. Thats it - put 1-2 FEX on top of every rack and connect it to the Nexus. Done! Pretty simple. But are they right about their decision?

p.s. our datacenter is splited in two locations on the same floor and basically consist of several enclosures and rack servers (about 10-12 racks of equipment).
