I've used NOD32 on all of my business and home computers exclusively for over 3 years. Before that, I had been a Norton user since v. 1.0 (yep, the DOS original). You won't ever find 100% agreement among various testers, but I think
Virus Bulletin has the most rigorous standards of any testing organization. You need to create a free user account to log on and look at the test archives, but you'll be able to check out years of test results for almost all vendors. The VB100 Awards are a terrific resource.
