A lot of that comes down to personal taste I think Neal. I have test worn TV a few times. I can't say I have a lot of knowledge of Back to Black, but if memory serves it's a very different vibe.
TV to me is prominent, sweet vanilla with a touch of tobacco. I can't describe BtoB in detail, but my take away is that it's a more complex scent. Not as sweet. Love to hear others weigh in.
