Use neither. I've had great success with AVIRA. Use that and run Malware Bytes once a week and you're in good shape.
It may be too early to say definitively, but I've been running the MSE beta for a couple months and like it. I upraded both home xp machines to the released code today. ARS Technica had a positive review for it today.
