hehe well one of my dog's Leo is a cross between the 2 and to be honest Goldens and Labs have the same personality although labs are more driven then Goldens.. Goldens tend to be more easy going and calm .. depending if you get a regular Golden cuz there are 2 types of Goldens .. the field, that have more energy and are more driven than the regular house Golden hence the name field to have that extra energy to work longer and same with labs.
But both are very very similar to each other .. so i go for both cuz Leo is both

and he's an angel !!
