If you have a particular breeder in mind for ACDs, it would depend on their particular dogs but as others have said I've known too many DA/DR/SSA ACDs to default recommend them for what you want. And depending on the body type they don't always make good agility dogs. But they are a cool breed if you are picky with what you get.
I've only met three related Koolies so can't speak to that. A Traveler clone would probably fit your list but if there is a Traveler clone he is MINE
Aussies again probably varies based on line. Some are pretty goofy lol. One with recent working lines, though...there are some very fun Aussies in this world. Stable, drivey, just enough assholeness to be fun, appropriate in social settings...
Ha. This is my life right now.
"I'm thinking my next dog may be a border collie."
"Oh for agility?"
"Well I'd like to do agility with him but mostly I just like the breed."
*blank stare*

That reminds me of the dog snobs post "(We refuse to believe anyone actually enjoys Border Collies.)"
