Can't go wrong with Nicoticket's H1N1, but it's a blend of other flavors, not a straight up tobacco. I'd still recommend gving it a try. Also check out Wakonda.
Not too long ago I ordered some NETs (naturally-extracted tobacco) from good ejuice that I liked. You'd probably enjoy patriot for a straight up tobacco. Vita Bella has some vanilla sweetness added. GJ4 is vanilla and caramel--my favorite.
Indigo has a well-reviewed NET lineup but I haven't ordered from them yet.
In general, if I want a straight tobacco flavor, I look for a NET. If I want a blend of tobacco and sweeter flavors, I'll try whatever.
Haven't tried H1N1, but Wakonda for a straight up tobacco ? nah. The tobacco is an afterthought at most imo, the real stars are coffee and vanilla.
OP, are you looking for cigarette flavored tobacco, or cigars or pipes ? You need to narrow your criteria a little to get better recommendations.
If you chose to go with NET's, remember with a few exceptions they gunk up your coils a lot more than synthetics. Well worth it though imo. Here's a list from the first post of the Natural Tobacco thread :

For synthetics, opinions are almost as diverse as the number of vendors out there. I don't vape them much anymore, but when i did i like Halo and Hangsen for straight tobacco synthetics.
