I voted for SFAM first, so the poll took that, now I can't change it.
I'd say SFAM is my second favorite of all those listed in this poll. It's a good representation of JLBs voice. It is exactly what it needed to be, when it was called for...
...but I would say my final vote would go to 6DOIT because the range JLB has on that album is clearly much better than SFAM. He goes from songs like TTTSTA, to GNK... from brutal and harsh to tender and loving.
That's not to say that his voice doesn't do that on SFAM, but on 6DOIT it's so much more noticeable and clean.
