STM32CubeF4 HAL Drivers vs. Compiler Suite

Hey guys, not sure if this is the right place to post this, but going forward, I am looking to purchase a compiler suite for the STM32F427ZI and one question I have is this:

If the STM32CubeF4 comes with the HAL drivers for CAN, USB and RTOS, does that mean I would not need to purchase a compiler suite that includes those as well? Just trying to figure out why someone would pay for a professional version if the STM32Cube does this already? Are the drivers supplied with compiler vendors better, more efficient, faster, etc??? Any help would be appreciated...

Thanks in advance!
