Wouldn't really make any difference. The last company I worked for did pretty much everything with MCU's based on ARM Cortex-M. All that shit's still not in stock anywhere. And remember that ARM, x86, etc. only defines the processor architecture. The I/O is far more important in a control application and I/O is anything but standard across platforms. For one product we ended up buying a vendors entire supply and redesigning the product to use it, crossing our fingers that the supply chain would have unwound itself by the time we ran out of inventory.
