I'm going to be the odd one out and say stay away from the GSDs. I'm a dog trainer, I've payed my rent of GSDs more times than I can count. It is VERY hard to find one with a good, stable temperament, good health, good joints, etc. etc. They are so over bred it's insane. Not to mention that the German lines have roached backs and the American show lines have hips that drag the ground. There is nothing about the conformation of a GSD that appeals to me.
Of course I say all this as someone who has two Aussies. So obviously I'm an Aussie person. I can however say that out of the dozens of GSDs and Aussies I've trained the Aussies win hands down when it comes to trainability and the ability to think for themselves. They are high energy, but if you train from puppyhood and give them a good run everyday it's nothing that cannot be channeled.
If you're wanting to do agility the Aussie is also your best bet because they're smaller and more agile that most GSDs.
Are there nice GSDs out there? Of course. There are nice, well behaved, healthy dogs of every breed. Personally I would never own one. The odds are against you when it comes to getting a good one even if you do your research.
