Is Cristal worth it?

I really want to try that Cristal champagne.  I am not sure if I'm attracted by the name, price of aura ... but as an enthusiastic champagne drinker I am wondering if it's really that good!

Right now my favorites are:

Verve Clicquot (orange label)

French Mumm

Schramsberg (the White House Champagne)

What's your favorite?
