Depends on you. All Tastes are Subjective.
Try several different kinds.
tobacco, Bakery, Sweets, Fruits, Drinks,.....
I started with Sweets / Bakery 3 1/2 years ago because I wanted something OTHER THAN
tobacco. Now I enjoy Tobacco flavors as well as sweets and bakery flavors.
Remember - Variety is the Spice of Life ! so go try samples from several different vendors.
