Free Zone Alarm or Pay McAffee

A lot of modern internet services and such are giving McAffee free with their service. I'm guessing this means it sucks. However, could it a sucky full version be better than a free good firewall like ZA? I'm curious because my service offers it but I'm still currently using ZA.

The piece of **** must suck. I haven't even had my computer for a month, and evidently something got by it, because my computer is in pretty bad shape. ):

It's a pile of ****. I got the firewall from them back when I was just about to get my Mac, and it seemed to worsen things. I've never tried Zone Alarm, but I bet anything is better than McAffee's junk.
