When simple pattern-matching and templating can express what you want, syntax-rules (and even define-syntax-rule) is great and very easy to use and read. When your macro needs to do more involved computation, that's when syntax-parse really starts to shine. As a rule of thumb, I usually try to write macros with define-syntax-rule first, then syntax-rules if it's not enough, and then syntax-parse for the more complicated cases.
