You can view a scissor style regulator as having several thick pieces of steel that keep the window in place. It’s sturdy, but needs a strong motor that often wears out before everything else.
Cable-operated window regulators use a near vertical cable to assist the window get into the right place. It’s a more compact design that puts less stress on the motor. But it is also more susceptible towards being damaged due to the increased stress that the pulley and cable must harness to raise and lower your window.
