Stepper motor driver differences?
Plain H bridges can be used to control large steppers, provided that they have the current/thermal capacity.  But it's not efficient to do so.

The problem with a stepper motor is that the windings have lots of reactive impedance, and a motor with fine steps, rotating at or above a moderate speed, will be trying to switch the current flowing through that inductance very quickly.  Doing this requires a quite high voltage - eventually many times the voltage necessary to push rated current through a stationary coil which shows only resistive impedance.

The designer of a simple driver has a choice: they can size the voltage for the stationary case, and lose torque (and soon miss steps) as the step rate increases.  Or they can size the voltage to overcome the inductance of the high speed case, and overdrive (and overheat) the motor when it is not turning.

An early solution was to use a very high voltage, and huge power resistors in series with the coils - in effect reducing the ratio between the total impedance in stationary and rotating cases.  This was actually done on some early CNC conversions of full size bridgeport milling machines, but effectively means there's a resistive heater strapped to the back of the cabinet.

The modern, efficient solution is a chopping current drive.  This is effectively an additional circuit which rapidly enables/disables an H bridge.  When a step occurs, the winding is energized at a high voltage.  A comparator then monitors the rise of current though the winding inductance over time (typically by sampling the voltage on a high power fractional-ohm sense resistor).  When the current has risen to a set point level, the driver is disabled and the current falls.  It's then re-enabled and the cycle repeats - as long as a given winding is commanded to be energized, it will be "chopped" on and off to achieve the specified current.

Ultimately a chopping drive is an H bridge - but one with an extra current regulator inserted between the step generator and the control signals to the FET's comprising the bridge.

NEMA23 is about at the dividing point for H bridge construction - anything much larger and you want an assembly of discrete power FET's, while for limited applications at that size and lower (desktop 3d printers, etc), you can probably use an integrated circuit bridge or complete driver circuit with chopper included.
