The beauty of CDs when they first came out was because they had room for more dynamic range than vinyl, but it got more and more abused as the years went on by record companies boost the volume of CDs louder and louder sacrificing the dynamics in the process. From what I've seen and heard recently, vinyl hasn't become a victim of that which is why I guess people opt for that rather than cd these days.

Vinyl is technically not "better" than cd, it's just CDs are poorly mastered these days.
