What is the main reason to split the decoupling/matching capacitors in the reference designs of power transistors?

 

We went through several reference designs of the power transistors, i.e. MW7IC2725N/A2I2D040N, and in general felt the the xpF capacitors were from ATC, xnF capacitors were from Kemet and xuF capacitors were from Murata. What is the main reason the split the capacitor suplliers like this? Can we replace ATC capacitors with other brands like Kemet or Murata by fullfilling some key parameters since ATC capacitors are very expensive? Thank you.
