All puppies are sweet! Who can say they're not the most adorable companions you could ask for?  They are all sweet, cuddly, wiggly, snuggly and affectionate. 

For some reason, many times people have a pre-determined idea that female puppies are easier to train and exhibit less aggressive behavior, but in actuality boys are just as easy. In fact, female puppies usually rule the roost, and are more independent and territorial. Females will let you know who's the boss right away and will try to establish dominance. Males are very playful, attentive, affectionate, and want to please you. They are also motivated by food (remember the way to love is through the stomach or something like that) and so males are quite easy to train. Boys love to play games and they are fun loving all their life. Females, as they age are a little more reserved. While the independent spunkiness of the female is attractive, so is the gentle, attentive calmness of a male. 

The one myth that needs to be debunked is that males are always "humping" or lifting their leg to potty on everything. If a male is neutered early, he rarely exhibits these traits. In fact, boys who are neutered around 6 months of age usually don't ever raise their leg to potty.  So when considering a puppy, don't forget the boys. They will win your heart and keep it!
