As a rue of thumb I would agree.  My go to reference is the portable
shell reference from GNU autotools (where portability is paramount):

    http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Portable-Shell.html#Portable-Shell

On the other hand if your doing devops and know a good deal about your
target environment you should feel free to use whatever is quickest to
write and easiest to maintain.
