"3. GnomeBaker
I think GnomeBaker is a little underrated by some. It has a simple interface, which kind of resembles the one of K3b, with the file explorer in the middle of the main window. GnomeBaker can burn CDs, DVDs, audio CDs, CD/DVD ISO images, it supports multisession mode, dragging and dropping files and projects. A very good alternative to Brasero for GNOME users."
