Well, after having the Linksys BEFSR41 and the RT314, I was much more impressed with the capabilities of the Netgear. The Zyxel version of the RT314 is pretty much the same thing with a few more options (SNMP being one of them).
The newer firmware updates to the BEFSR41 allow you to tie in ZoneAlarm with the router somehow, but since I got rid of mine before that support came in, I don't really know how well that works.
