Aventus vs Tobacco Vanille. Then Back To Black vs Tobacco Vanille. It's pretty obvious you're into Tobacco Vanille. Have you actually smelled it, or are you just reading stuff online? The only sure way to compare two scents you're interested in is to buy samples and give them a proper wear.
Back To Black is a very different scent than TV. They're miles apart. I bought a sample of Back To Black thinking I'd love it, but even though it's very good, though it's not my style. And that's an important point I think a lot of people don't understand. STYLE. Style is a personal thing. It's about what fits you as an individual. For me, Gucci Pour Homme II is like a compliment machine. If I wear it on a date, I'm almost sure to get a compliment, but it might not work as well for you if it doesn't fit your style and your personality. Lots of guys here rave about Back To Black. Use the search and you'll find a ton of info on it, but the only way to know if it would work for you is to smell it and give it a test wear - or, better yet, a few test wears. Which one of these two scents a bunch of guys on the internet prefer isn't going to tell you which of the two you'd prefer. For me, the answer is TV without a doubt - but I'm not you.
