Common Lisp is too hard.

I still can't get my head around prefix notation. I heard Scheme is easier though. Seriously, why do practitioners of Lisp-like languages claim it's so good? I honestly cannot see the big deal, it's an old, slow, awkward and overall clunky language to use.

int a = 4 * (73 + 5);
As opposed to
(setf a (funcall #'* 4 (+ 73 5)))
Tell me which one is easier to read (HINT: it's not the latter)
