No, although it sounds easy the way I put it, there is actually some more thinking behind it. You can't use a B-17 like a Stuka, so your conclusion doesn't make sense.
The Stuka was very effective the way it was used for pin-point attacks, it was accurate not because of the aircraft design or systems, but because of the dive bombing. It didn't have the range, power, speed or weapons to make it that big of a deal. German pre-war aircraft designs for combat aircraft were poor, and the Stuka was one of the designs from that time.
The B-17 had power, range, robust design. Okay not all perfect maybe. But losses would be less if not deployed at day time over Germany.
For the Stuka, the tactics were designed for the plane.
For the B-17, the plane was designed for the tactics.
Anyway, it's like comparing apples and uhm...bananas
