Mosfet drivers are going to be better for a few reasons.  Firstly,
they have a high input impedance so no need to worry about drive
requirements.  Secondly, they are designed exactly for this purpose!
They are specially designed to avoid cross conduction inside of the
driver itself.  Most of those gate driver schemes that use discrete
components require some tweaking to avoid both transistors being ON at
the same time during the transitional period.
