You won't regret either one.
I wrestled with this very same decision not more than a few weeks ago.
In the end, I went with whatever better deal came along first - which happened to be a 2009 BMW F800GS.
I have zero regrets.
That being said, had I bought the Tiger, I probably would also have zero regrets.
By all accounts these bikes are very similar - picking the better one is an exercise in splitting hairs.
Get whichever you get a better deal on is my advice.
