Not many can argue against this one. K3b is the most popular burning application for Linux, and although it uses KDE3 libraries, many GNOME users prefer it too over native GTK burners.

The version I'm going to talk about is 1.0.5 for KDE3, but K3b 2.0 for KDE4 is in the works, and the second alpha was made available for testing purposes earlier this year. You can read my review of K3b 2.0 Alpha 1 here.
K3b can burn anything, from audio CDs to DVDs or ISO images. It allows you to save the projects, it includes a powerful file explorer and an easy to use interface. You can also use K3b to create CD/DVD ISO images, it supports projects, multisession mode and ripping video DVDs.
Brasero is the default GNOME burning application. As usual, it features a simple interface which integrates very well in GNOME, with five large buttons for fast access to the most common actions:
- Audio project, to create an audio CD
- Data project, to create a data CD or DVD
- Video project, to create a video DVD or SVCD
- Disc copy, to copy a CD or DVD
- Burn image, to burn CD/DVD ISO images

The nice thing I found about Brasero is that it also includes a simple but useful cover editor for your CDs or DVDs.

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.

Several others are also worth mentioning. We have MyBashBurn, which is a wonderful text user interface frontend to cdrtools and growisofs for burning CDs/DVDs, it supports multisession and burning ISO images too.
There is also Nero Linux, which is great, but unfortunately closed-source, from the same project which does Nero for Windows. A trial version is available for download here. In Ubuntu, just download the (currently) nerolinux-184.108.40.206-x86.deb file and use sudo dpkg -i nerolinux-220.127.116.11-x86.deb to install it.
