I've just checked the bash man page, and there's no difference. Using backquotes is described as the old style. OK, there is one difference; when it comes to nesting commands, you have to quote the nested opening/closing backquotes, or they are taken as the end of the first command. There's no need to quote the opening $( though. As Matthew said, it's all down to readability...
