Both breeds are intelligent. Labs are easy to train. Huskies can be escape artists, they can also talk
Just adding on to this: Huskies can be a pain to train (stubborn aren't biddable)
If you raised pups, then you know they whine for the first 3 nights (get earplugs), try to ignore him. Good Luck.
Both breeds are nippy, train Bite Inhibition (See the Sticky: The Bite Stops Here).
You can train a Lab to walk off-leash. I don't think that you can trust a husky off-leash ???
You should never fully trust a Siberian off leash unless you're in fully enclosed area. It is possible - but it will take training from the very beginning and you will never have 100% perfect recall. (that applies for any breed because there will always be that one time you can't call the dog off)
