I've read a lot of Asimov, and I must have first come across this marvelous collection back in the mid-to-late nineties. I enjoyed almost every story present, although the first section didn't appeal to me as much, and A Boy's Best Friend in particular was not very well developed (Robbie was much better).

I think my favourite story of the book has to be Victory Unintentional, although Powell and Donovan and Calvin are huge and I also really enjoyed Reason, Galley Slave and Feminine Intuition. A highly recommended collection indeed.
