It is obvious that this is a very hot topic and I imagine it would depend on who you ask as to the answer you would get when it comes to s/n.
Mostly, this topic has focused on dogs, but I would like to interject an opinion when it comes to cats. My experience, as it relates to neuter vs. vasectomies, is with "big cats" and "exotics". At the facility that I worked at (a rescue organization) we took in many felids that had been used for producing "babies" to sell. All were intact and some even came to us already bred, which meant we took in more than we expected. Since we were not in it for producing MORE exotic animals, we had to steralize.
We opted to vasectomize the males, as it is alot easier to perform this surgery in the field, than it would be a spay. Since we weren't going to spay the females, the males HAD to remain driven to "mate" in order to keep the females ovulating. If they were never stimulated to ovulate, there could have been some very sick female cats on our hands. Also, the teste's produce the necessary hormones that ensure that the males REMAIN male with in thier prides. If they had been removed, males would have lost their manes (in the case of the lions) and would have been killed by the females as they would have appeared "sick" or "weak". The tigers, while mostly solitary animals, were kept in very small groups, and again, the males would have appeared sick or weak to the females if they had been neutered.
There is also evidence that indicates higher risk for urinary tract problems (that can be life threatening) in neutered male cats.
I know that this is not realivent in terms of domestic pets, but it does prove that removing the gonads does produce an animal that is not equal to it's intact counterpart.
As far as JQP, I do believe that S/N is a viable alternative to accidental breedings, as well as, indiscriminate breeders creating poor quality examples of pure bred dogs for profit. However, I'm not a huge fan of early S/N for adolescent pets when in the hands of competent, knowledgable

et guardians.
