It doesnt matter where a wine comes from or how much a bottle of wine costs.
The best wine is the wine that tastes the best TO YOU. Really its that simple.
That being said, my favorite is Trilogy by Flora Springs in Napa Valley. I've been to their vineyard twice and the tour there is great, check it out if you are ever in the area.

At $65 per bottle its just a tad expensive, but its not meant for every day drinking.
