Sophos here, just rolling out NAC at the moment.
Regarding SAV, no issues other than it doesn't automatically clear PUA/Adware all of the time, and you have to manually clear it off the client - where as with Kaspersky click to remove and it's gone, no messing about!
NAC we've found a bit fiddly, we've had to introduce gradually due it's tendancy to shut everything out of the network and mis-identify endpoints and the like. I wouldn't opt for it again, given the choice - documentation is poor, the gui/console feels overmanaged, and the DHCP Enforcer/Radius setup doesn't work properly for us (at the moment).
Sophos Puremessage, worth a try if you haven't already, complements our Sonic appliances very well (for spam and email bound virus control).
