ROTTWEILER or GERMAN SHEPARD or SIBERIAN HUSKY?

My family and i just move to a big house and we have a pretty big backyard, I have always wanted to own a dog, but never got one. My only 3 favourite types of dogs are ROTTWEILER, GERMAN SHEPARD, and SIBERIAN HUSKY, I read few books and these book recommend this types of dogs only for experienced dog owners, but I really like these dog and wouldn’t get anything other than one of them. I really hate grooming but if little I can manager it for them, I live in Canada which means most of times it is cold weather here and snows a lot…My question is which one of these dogs would be the best choice for me? And do I need to pay a monthly insurance for the dogs as well?
