Most serious mead drinkers don't consider Bunratty, a wine/mead blend, a serious mead. I like the Polish meads - Jadwiga, Slowianski, Lednicki, and Kurplowski and they always do very well at the International Mead Festival. Ring of Fire, Rabbit's Foot, Redstone, Mountain Meadows, and Pirtle are all good choices.
The best meads are typically non-commercial. Those who are in the business demand a profit and mead's expensive to make when using quality ingredients. The best meads I've had were made by gifted amateurs.
Stay away from the most likely candidate you'll find at your local liquor store - Chaucer.
