Translation of "Inigualable" in English

and unrivaled opportunity.

El Corán, lejos de ser inigualable, es más bien una obra literaria de calidad inferior, no es claro, ni entendible, y no posee valor práctico y definitivamente no es un libro revelado.

The Koran, far from being inimitable, is a literary work of inferior quality, as it is neither clear, nor understandable, nor does it possess any practical value and is certainly not a revealed book.
