Comparing Mcafee vs Norton corporate

I am in the process on selecting an appropriate antivirus program for our bussiness environment, i am presently reviewing MCafee and Norton.
I am looking to be able to have a centralized management to servers and Workstations across VPN connections. One of the most important points is to the centralized mgt and send the updates fast and effectively
The reviews on the each brand website is very much the same, they claim to do the same.
MCfee is more upfront to compare its ePolicy Orchestrator(management tool) to have few more features.
I am looking to hear some comments for existing users of any of these products.

Is Mcafee better? for Manageability perspective, how is the new incremental updates.

Thanks in advance
