To make the point, one of the popular Hall sensors on these forums is actually categorized by the manufacturer as a transmission speed sensor, not crank or cam. Use whatever has the qualities you need for your setup to work well, as @dzener did. Even minor differences may mean a different sensor than what the next user found to work well. Just because one type worked or did not work for you doesn't mean success or failure to other setups, IMO.

That said, the most common issues are instead related to sensor aperture (how many or enough of one tooth it can see at one time), minimum target (tooth) size, and depth (readable height of teeth)affecting reading at any speed. There are several factors to consider with sensors and target features (wheels and teeth, holes, slots, etc) and reliable function. Unfortunately, most specifications are not available, and you end-up testing for results.
