It depends on the property. For a property that assumes a string value (caption of a label) the = sign means evaluate the expression so
=""
is an empty string while
""
would show two double-quotes.

I know I've done it in the past, but I don't remember exactly why and I don't have the form in front of me now for a reminder.
