Size
The Alaskan Malamute is a little larger on average: about 36 kg (80 lb) as an adult, against 29 kg (65 lb) for the Chinook.
Temperament
They differ most on independence (Alaskan Malamute: decides for itself; Chinook: keen to work with you) and on prey drive (Alaskan Malamute: likely to chase small pets; Chinook: usually fine with small pets).
Neither is the better dog in general. Which suits you depends on your home, your days and the care you can give.
