I agree with this.

I don't agree.  Show me a painful simple use.  Pick any simple
macro you want: let, let*, or, and, cond, case, or any other
macro of your choice to show the pain.

I don't agree that defmacro is easy to use without a pattern
matching facility.  Again, write the example that you provide
(above) using defmacro; I doubt it will be simpler or easier
or more robust, or anything.
