Total package, I'd have to go with EZCD creator. If you have specific needs, psx concerns, etc, then maybe you'd like CDRWIN, but most people don't have any concern over which bits are written to which sector of the ROM. :O)
If copying disks and burning data to a CD is what you're after, you can't go wrong with the Adaptec stuff. They're support for drives is great, as well.
