I tried PC-BSD, which is FreeBSD with a graphical installer and configured to work on a desktop. I tried the 32 bit and 64 bit versions and I found them to be too buggy at this stage of their development. I got them working but I had to re-install each a number of times. I finally gave up after the 32 bit version, which initially worked, began to freeze on boot. I was using an ASUS laptop with ATI video, and Atheros wireless.
Don't try OpenBSD unless you're an experienced Linux user or want to spend some time learning to install and configure it.
For stability and ease of use, you can try PCLinuxOS, Ubuntu, Fedora, Mint, or Mepis. You will be happy with any of them, however, Ubuntu has the larger user base, which means it also has the largest support Forum.
