== is a strict character by character string comparison.

=

Anything that can resolve to a numeric value is resolved and then compared
mathematically.  Leading and trailing blanks are stripped.  Case sensitive.

==

Strictly a string comparison.  Blanks are not stripped.  Case sensitive.

== is faster than = because of the lack of preprocessing.  It is also safer if 
all you are interested in is a character by character comparison.
