I have yet to find a BEST. Of course, I am one who is always disappointed in sunsets. My anticipation of what it's going to be like, and then when it happens... "well, that was nice, but..." But, nothing in pipe tobaccos or sunsets have really rocked my world. I mean, I get 9/10's a lot. But, none have been a 10/10. I did smoke one aged Cuban cigar, which did rock my world, but no pipe tobacco has ever done that for me.
I mean, I enjoy smoking my pipes, but really... I mean, as long as it's not an aromatic, or it isn't cased with something that ruins that damned smoke... some that people have posted are their favorites, repulse me by being too heavily cased, IMO. But, I hold the 10 level of ranking for that one tobacco that I will meet one day that just gives me a sublime experience to rival no other.
I'm picky, I know. But, I'm just not about to start giving out 10's to "OK" tobaccos or ugly girls with nice tits. YMMV.
