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....

The blur should be roughly the same (just multiply the focal length by 1.4x per f-stop). However, the 60mm catches more background in terms of field of view. There has always been a debate about the "perfect" focal length for portraits - typically this is considered to be somewhere between 90mm and 135mm (full format) and both fall into this range. The choice is yours. ;-)
