Difference between Itunes backup to disc and Toast method?

[benlee]

What is the diffence between using itunes backup to disc method and using toast to burn data dvds. I have 40 GBs of music and I'm backing up in preparation of Leopard. I already have it all on a bootable copy on my external but can't risk losing it all so want to have a backup for my backup.
So which method is best to use?

I am not suggesting which method is best to use.

iTunes backup to disc allows future backups to be made incrementally (only items added since your last backup). This can save time and discs.
