Alright, the deal with the ZA suite is that it might honestly be the best one available, but it slows down start up a little.(which is annoying for me because I'm constantly wipping out my laptop for quick 10 minute things) but I've found that its much less of an issue if I have it not start up with windows and only run it when I'm not at home.(behind my router firewall)
The AV in the suite is Kaspersky(big plus) and the Firewall is rock solid and probably the best out of any of them. The only problem is if you have the whole suite running ram usage can get up there.(but you have a brand new beast of a computer, so you wont mind. ) My laptop is no slouch either so it runs really smoothly.
If you don't mind waiting say 30 seconds longer for start up then by all means go for it.
