It doesn't matter who wins. Look at all the past contestants who have wonderful success and they didn't win.
Chris Daughtry
Clay Aiken
Jennifer Hudson
Kat McPhee
Adam Lambert

There are LOTS more but I can't think of them right now.

Also, the second place person usually releases an album before the winner does.

I didn't care who won because I really like both of them equally. So it's a win-win for me!
