For quality, I'd say yes. It depends, i imagine some feminized photo period plants are awful, and some are banging.
For quantity, I'd say it depends how long you vegged your photo-period for before inducing flower. After 6 months plus of veg & 3 months flower, I imagine you would produce more pot that you would have if you'd have grown an auto start to finish in 3 months.
If you do some research, and pick quality genetics, I'm sure the best Autos are up there with the best Photos.
