Hi,
I am considering one of these on D5100.
The usage will be mostly portraiture and candid street and occasional macro.
Was wondering which of these two lenses will blur the background more, when used wide open?
One is a stop faster, but shorter...and the other is slower but longer....
Lets say for a head and shoulder portrait....

Considering we frame the subject similarly, the blur is mostly a function of the size of the aperture.
90mm / 2.8 = 32mm aperture
60mm / 2 = 30mm aperture.
As Klaus said, the blur will be about the same. It is more about field of view, which you prefer. I prefer the more narrow field of view myself, that then would be the Tamron 90mm. Which field of view you prefer is something you have to decide on yourself...
The 60mm f2 probably is a bit better wide open.
