In my experience, that is an overgeneralization, though definitely a tempting one that is frequently encountered.

That being said, I find that Prolog code is often more readable than Lisp code. An important reason for this is that Prolog supports prefix, infix and postfix operators that can be defined as part of the concrete syntax. On the level of the abstract syntax tree, all terms conform to the inductive definition, so this is only a notational convenience.
