I prefer Security Essentials.

It's the on access scanning component which can cause problems when both are enabled. Basically each time a file is accessed it is automatically scanned. When you have two anti-virus programs scanning automatically in this way it can cause noticeable delays and at times mess things up badly if something screws up and they interact poorly with one another. What people usually do is disable one of the on access scanners and use the other one just for manual scans.
