I like it. Not just because I did the icon. It's pretty much a front end—supports joliet and ISO 9660 (whatever those are—PC format discs, right?). You can create and save burn lists now, I believe. There's some kinks Bryan, the author, is working out, but it's going well. He has plenty of more stuff planned for it. Eventually you'll be able to create DMGs. It'll burn music discs, too. He's just ... got stuff planned.

Check out the RadicalBreeze forum—he'll answer any questions you have about the product; he's quite an active developer. He's aiming for it to be a good competition for toast.
