I always opt for neutering at an earlier age--partly for the reasons Maryellen notes. The "kids" really don't seem to have issues with the surgery as opposed to some older dogs who tend to worry the incision or just in general take longer to recover.
Our rescue has a vet that will do the pediatric neuters, which is what I want because I just don't want to adopt out an intact dog--I've only done it twice in my life but I kept on those pups' owners till I got the speuter certificates, and I know I was a PITA till I got them!
I've never really understood the complaint that the pup might turn out to be "leggy" or whatever because I've never noticed it in pet dogs. I mean, when it comes down to it, if someone put two pet dogs down in front of me at 1 year and said, 'pick the one neutered at 8 weeks and the one neutered at a year,' I doubt I could tell the diff. And I have yet to meet an owner who has told me that his/her dog had growing issues because of early speuter . . . despite the fact that there are people out there in the ether who claim it has adverse affects, causes growth issues, etc. I honestly just haven't seen the proof that this is the case.
I don't have a problem with people keeping their pus intact till 6 mos. or more if they feel they must do so, IF they are able/willing/understanding of the need to keep that dog from getting near females in heat. But I honestly dunno that the average pet owner would really see any negative consequences in a dog neutered early. Maybe I'm wrong, but I know lots of dogs neutered quite young who stack up pretty well to the boys who've kept their, um, boys till an older age.
