It depends on how you set it up.
If you just want core parking disabled while X app is running or when system is not idling, PL will do this fine,
you have all options and features it brings.
If you want to manually edit one or all of power plans Park contorl does this, my guess you have the boost feature enabled and that is why your in BHP mode.
It all depends on what your trying to do as what needs to be installed or running on the system.
