Pro's: Reduced component count. Cons: Significantly reduced brightness in comparison to direct drive at equal cathode current. Visible flicker- like POV, accentuated at periphery of vision. Audible noise, or buzzing. PWM with direct drive is also a common feature of many clock designs to control display brightness.
