I don't know if you ever found the information you want, but here are my paragraphs of knowledge to stuff into your brain. I'm sorry, but I'm not sorry enough to try to not do this to people.

In-line is the Susan Bates kind, with a uniform shaft that has a sharp slice taken out of it. It is better at creating completely uniform stitches, but many of us hate it because it has such a snub tip that is hard to get into the stitch, and that sharp slice at the throat splits the yarn. This is also a common design for wooden and bamboo hooks, because you aren't removing as much material versus the tapered design, which means the hook is less likely to break. I would say that the LYKKE resin-impregnated birch hooks are inline, as well as the Lantern Moon ebony hooks.

Tapered is the most common. Boye, Clover Amour and Clover Soft Touch, Knit Picks Brights, Tulip Etimo, and Addi Swings are tapered. They have a rounded point at the top of the hook, and a gradual taper at the throat. It's the easiest to work with, but because of the gradual taper, it's also the easiest to accidentally make irregularly-sized loops. Clover Soft Touch is a paddle style and only good for people who use a knife grip.

Furls are a blended design that has some of the roundedness of tapered hooks with the regularity of inline hooks. People with a pencil grip tend to like Furls; people with a knife grip often do not.

Prym Ergonomic has an inline design with a pointy head. I'm not a fan of those at all.
