I prefer Adele's voice so much. Jessie J is a fantastic song writer because she too writes from experience - "Who's Laughing Now" is a prime example - but she has a style that will only really appeal to one particular group of people because of its style, and I also think it's the sort that, in a few years time, we might look back on and think "Did we really think that was amazing?", in the similar way some people do for Steps, S Club 7, Atomic Kitten etc these days - I honestly think that the songs Adele writes and her voice has something timeless about it, where the style won't feel dated or anything.
