My two pence:

I actually use both EZ CD and Nero, each for different things, because I find that each one has strengths and weaknesses. I have both installed on my home PC.

On our "Master shipment files" server here at work, we use a very old version of EZ CD (version 3 or 4 I don't remember) and a very old Yamaha 4x external SCSI burner for our final shipment discs. Reason: Everything is rock stable, never makes a coaster, and we always only burn discs one specific way.
