There are cockroaches and cockroaches. As far as I'm aware, there is only one species of cricket sold in the US as a feeder, 2 species in Europe and I'm not sure elsewhere. There are many different types of cockroach, with variations on the nutrition info you've posted and different chitin:meat ratios. Unlike crickets, it's hard to pigeon-hole cockroaches, not to mention that I doubt anyone would feed an American cockroach to their pet.
