Quartzite could indeed be more durable. Granite? I'm not a fan of granite in bathrooms. But I really don't much like granite at all. If you're doing a marble basket weave on the floor, I'll come over your house myself and tear out the cultured marble top if you have that installed. ; )

I would encourage you to find a nice piece of marble and go with it. Your personality seems suited to marble. A fine piece of marble? In many ways it's unlike anything else out other.

At times people lose sight of the fact that it's a living space. It's not a museum. You can get into habit patterns with lotions and potions that can minimize spills on to the marble.

What ever you choose...enjoy! Unless you choose cultured marble. Don't say I didn't warn you! lol
