You might find it interesting to read the Cook's Illustrated Vanilla tasting results.

Now I just use a bulk size vanilla I buy at Price/Costco for everyday needs, McCormick Pure Vanilla extract $5.99 for 16 ounces. For something special I use Nielsen-Massey Madagascar Bourbon pure vanilla extract. I was lucky to find a stash of it at the local Ross discount store for $6.99 for 8 ounces. It is usually $11 or $12.
If you click on the chart at the end of the article you will see tasting notes by brand. The two I use happen to be the top rated brands. The panel members are fairly distinguished bakers.
