Lab hair, being short, falls out constantly, and scatters, sticking to EVERYTHING.
Golden hair, being long, falls out, but usually sticks to their body a bit more, and when it does fall, it kind of clumps together, making little furballs all over the place.
They both shed year round, with labs being more consistent, where Goldens shed more heavily in the spring/fall.
I prefer Golden hair, personally.
