CD Burning Software


I've used a few software programs in my day. Currently using a Free and old version of Ashampoo version 6.76. Was wondering if anyone can convince me to use something better, however, still "free". Also, if recommending something better please explain why. Thanks.

I use XLD on my Mac. Free.  Also provides conversion between formats. Fairly easy to use. Has a kind of barebones interface that has grown on me. 
+1 XLD confirms bitperfect rips. Works like a charm. Cheers,
