I used to use Mountain Lion at home but I've downgraded back to Lion. Unfortunately, there's an issue that causes audio stuttering, which has forced me to hold off on upgrading my Macs in work. This issue has been complained about on the Apple Forums* and 10.8.1 hasn't fixed the issue. I'm going to hold off on upgrading until this issue has been fixed.
* I'm unable to post links at the moment! Feel free to google "audio skipping mountain lion" to read CNET's report on the issue.
