Can't say that I know that much about different designes on focusers, but. A helical focuser as I've understod it is when you have to screw the whole eyepiece around to reach focus. The crayford focuser is much more rigid than the rack&pinion "standard" focuser and you can bet that it's a heck of a lot faster than the helical!
:) hope this helps.
