It's been a while since I needed to do any serious reverse engineering work, but I do remember IDA pro having support for a range of obscure CPUs, not sure how ghidra compares on that front these days.

Ghidra still mostly relies on community plugins for obscure platform support. It's ~OK but less than ideal.
They're both amazing, they're both quirky, and they're both buggy. But one is free and the other has its support. Pick which one matters to you :-)
