Least bad Altadis.
I think that's kind of like asking where's the best place is to get a boil.
Okay - an honest question deserves an honest answer. Here's my best shot. Once I received a free Altadis Montecristo White Torpedo. I think it was a sample. It wasn't bad in the sense it had some decent flavor and the construction was pretty good. While I won't judge any cigar based on a sample of one, and I wouldn't run out and buy more considering their price point, I'd probably smoke another if it were given to me.
Now should the embargo end, ask me again about Altadis.
