Initially Bourne was used because it was typically a static binary, because the boot process didn't have access to any shared libraries. When that changed it became a bit of a moot point, and you started to see other interpreters being used. Even though Solaris started using ksh as the default user environment, almost all of the start scrips were either bourne or bash scripts. With Bash having more functionality the scripts typically used the environment that suited the requirements best. Bottom line is use what ever script suits your needs just be sure to tell the environment which interpreter to use. Personally I never write a script that doesn't include the interpreter on the first line.
