VPC vs EtherChannel

I have 2 scenarios.
Scenario:1 - I have 2 Nexus 5K which are connecting to the 2 Nexus 7K usign vPC. The vPC is running at both the Nexus 5K & 7K.

Scenario:2 -  I have 2 Nexus 5K which are connecting to the 2 Catalyst 6509 which are in VSS. The vPC is running on the Nexus 5K.

What is the difference between the above 2 scenarios & how they differ.How the traffic flow differ between the above 2 scenarios.

From a traffic flow perspective, there is no difference.

From a configuration perspective, the difference is night and day.

With VSS, the two switches are configured as if they are one. It's really no different than a stack 3850's. You may have two (or more) switches in the stack, but there's only one configuration.

With vPC, the two switches each have their own configuration. vPC is just another protocol (like STP, OSPF, HSRP, etc.) that is configured on each switch. If the protocol is not configured correctly, then it won't work.

I will say that from an ease of configuration standpoint, VSS is much easier since all you're doing is creating a channel-group like you would on any other switch. While with vPC, there are a number of new (to someone who hasn't worked with vPC) configuration steps that must be done.

So in this case for both the scenarios all the uplinks from the Nexus 5K to Nexus 7K /Cat 6509 will be utilized.
No link will be ideal in both the scenarios. Let me know if the understanding is right.

Scenario-1:
N5K#1 - 1 10G link to N7K#1 & 1  10G link to N7K#2
N5K#2 - 1 10G link to N7K#1 & 1  10G link to N7K#2

Scenario-2:
N5K#1 - 1 10G link to 6509#1 & 1  10G link to 6509#2
N5K#2 - 1 10G link to 6509#1 & 1  10G link to 6509#2

In both the scenarios all the uplinks will be utilized & all the links will be active.

Sorry, I don't understand what you're asking.
