Which Harmonica is better for blues, a Hohner Special 20 or a Hohner Blues Harp?

Hey, I am about to buy a harmonica to mostly play blues stuff. After a few hours of research, it seems the best two harmonicas would be a Hohner Special 20 or a Hohner Blues Harp. Unfortunately, Lee Oskars are not available at my local store, and I don't want to buy over the internet. Thanks
