Read our New Growers' FAQ, linked in the menu bar. It also discusses classes.
The secret is that USDA "use classes" for tobacco were created to reflect how specific varieties were used commercially during the late 19th century. Actual tobacco varieties represent a continuum of nicotine strength, sugar content and floral aromas. I've made cigars from every variety. I've made pipe tobacco from cigar varieties. I've made pipe blends with every variety imaginable. Don't bother to consider statements that assign food aromas and tastes to tobacco varieties. That's all fantasy, and the inventions of marketeers for commercial tobacco products. For me, the primary consideration is the resulting pH (acidity) of their combination.
Flue-cured varieties and Orientals will produce excellent tobacco when either sun-cured or flue-cured. Burley varieties are uniformly awful when processed either of those ways.
Try some varieties for your own uses, and decide what you prefer.
