They are about the same,
some say JG Blue is better but they have changed them plus there is a similar looking ferrite version - maybe not with blue top but a ferrite high power one does exist.
SHS are pretty decent and they have fuller or stronger magnets inside:
SHS TORQUE is on left
JG BLUE is on right - note how the magnets taper at top/bottom which may not provide a fully strong magnetic field at these points....
