There are a few differences between Catalyst switches and Nexus switches.
The nexus n5k / n2k switches are a completely different architecture which use different software. I haven't played with them, but they show promise.
Another major difference is the integration of Nexus 2000 Fabric Extenders with Nexus 5000 switches. The Nexus 2000 switches basically act as remote (over 10Gig fiber) "linecards" of the Nexus 5000. This allows deploying top of the rack switches without the additional management overhead:
The N2K only support 1000 connections, not 10/100. So if you have slower speed kit like console servers or tiny boxes or whatever, you will need to cope with these separately. This is noted obliquely in the documentation:
