Norton NIS 2009 Premier Edition vs. Norton 360 v.3

I got the NIS 2009 with my new computer and my 60 day trial is about to expire.  I downloaded a trial for the Norton 360 v. 3 last night, and it seemed to use a more resources. I like the layout of the NIS 2009 better, but it’s not that big an issue.  I’m not really concerned about backing up files.  Fry’s Electronics has a great deal on the NIS 2009 Premier Edition–I have the “regular” Nis 2009 on my computer now…  My question is which program has the better security —firewall, Anti-bot, anti-keylogging, anti-virus, anti-malware, etc…  I’m not interested in all the bells and whistles with backing up my files.  Which is the better program to meet my need the NIS 2009 Premeir Edition or the 360 v.3???   Thanks.
