Could You Please Give Me The Pros And Cons Of Having A Havanese And/or Cavalier King Charles Spaniel?

Please give me some info on one or both of those dogs. Thanks!!

Havanese Or King Charles Cavalier?

I’ve narrowed down my puppy search to these two breeds. I love the temperment and look of both breeds but have no actual experience with either.
I’m a stay at home Mom and so I have lots of time to devote to care and training of a puppy. We have a large lab, three kids and two indoor cats and so I was wondering if anyone had an opinion on which would be the better choice for my family.
Thanks
