MCAS runaway is worse than a classical runaway, not only because it is an intermittent runaway, but even more so because it is caused by a faulty AOA reading that also drives the Elevator Feel System to MULTIPLY BY 4 the force opposing the pilot pitch up force on the control column.
The combination of high speed trim runaway AND elevator force multiplied by 4 is a killer.
