I dont think there is a Best Region. Some of us do have our favorites to either dance or teach. Personally I love Yucatan and it is My favorite. Although I really do Love Guerrero as well.
I agree i dont think there is a best, just personal preference. I love Nayarit, and I really love the dance and music to Viva Vera Cruz.. i dont know why but its beautiful.
We love Guerrero, Costa Chica y Veracruz. But I think like the rest of the members, all the regions have their unique style, all of them are beautiful.
