I grew up with goldens before my dad started getting labs so I have seen both. I think that either are great people dogs though labs seem to be busier and a little bit more of a bulldozer.
I just got my first dog, a golden. She is a great duck dog and absolutely loves it.
My dad just got a lab pup, they are two weeks apart. She is a better swimmer, more rambunctious but very cautious. My golden is the leader of the two.
I don't think you can go wrong with either, I just love goldens because I grew up with them.
