I'm not saying it's bad, I've used birch plywood myself and I like it.
But you can't compare the 13 layer plywood made from peeled wood with the stuff made from 3 layers of sawed wood. They are completely different types of product, and the cost is also very different.
Apart from mechanical properties, the 3 layer stuff is also much nicer optically usually (eg. they use camera sorted boards to achieve nice and even patterns). That's why it is more expensive.
