Also note that AppleScript is going to do things slightly differently
than raw apple events
A script like
tell application "MS Word"
end tell
launches MS Word first (by name) and then executes whatever script
you tell it to execute.
Raw AppleEvents don't usually do this unless you add in the
appropriate code to do this.
However, unless you write your AppleScript specially you can run into
issues if people rename applications (they do this)
Raw apple events do not have this same issue
But you can write a script that is also not sensitive to application
name, it just takes some work
As Christian mentioned though, the scripts are not precompiled and so
there can be some "start up" cost associated with executing one.
If you dont use MBS there is no way around this that I am aware of
