Eset Smart Security versus KIS 2009

I currently have KIS 2009. I used to have NOD 32, switched to KIS when I installed Vista. Since then, Eset Smart Security has come out and been out for awhile.

I've read on othe forums that the anti virus portion of Eset Smart Security is still as great as NOD 32 was, but the comments about the firewall are mixed. Has anyone here used both KIS 2009 and Eset Smart Security? If so, I'd like to hear your thoughts on both of them.
