We had this same question about 3 years back and I'm not sure that
anything has changed, but take this for what it's worth. The Nexus 5k
line uses cut-through switching where your traditional catalyst line
switches are store and forward. Here's a good link on this topic:
http://www.cisco.com/c/en/us/products/collateral/switches/nexus-5020-switch/white_paper_c11-465436.html
Also, the Nexus line may not have features that you want in a campus,
such as layer 2 protections like dhcp snooping, DAI, etc... That said,
just make sure you know what features you need, including IPv6 features,
which without verifying, I'm guessing are more plentiful in the Catalyst
line.
Hope that helps.

Thanks Michele for sharing the feedback you received on this.
Our cisco sales rep is telling us that he has never heard of Nexus used as
a campus distribution-layer and is trying to convince us that that Catalyst
6807 is the right choice (instead of Nexus 56128P), even though we would
get less 10Gig port-density, 1:2 oversubscription, 5x more RU used, at
least twice the power consumption, etc... and all of this for twice the
price!
Are there other people out there using Nexus (3x00 ? 5x00? 6x00 7x00?) at
the distribution-layer of medium-sized campus?
Medium-sized being about 60 access-layer closets with dual 10 Gig uplink
each and a small server-farm.
On the downside I hear that the "orphan port" scenario with vPC may be a
pain in the back side? I still need to read the details of this.
Is anyone running vPC at the distribution-layer of a campus environment?
Thanks

Does anybody have success/horror stories about the [Nexus] 3064 or 3048 to
share? If you email me in private, I can post an anonimized summary.
I received two very helpful replies.
One person told me about some new 3172PQ: "I am loving them to death".
This person is using them as L2, with vPC.
One person is using the 3064X with OSPF, BGP VRRP and is happy with it.
This is very similar to what I am trying to do.
I still feel a bit uneasy, but I think we will end up trusting the
datasheet.
Cheers to all,
Bergonz
