I guess I never questioned the words, "it's preferable" that I saw in my Guru Labs training material, but I can only confidently say that the $() form is preferred by me after several incidents of confusion and/or mangling involving back-ticks.  I'll have a short-list here:

 - It seems like more people know what a "dollar sign", "left/open parenthesis", and "right/close parenthesis" are, than know what a "back-tick" is.
 - It is easier to understand nested expansions of the form "$(runthird $(runsecond $(runfirst)))", than "`runthird `runsecond `runfirst```"
 - Word processors ~and~ people mix up single-quotes, apostrophes, and back-ticks.  Sometimes meaningfully and sometimes inentionally.
