One thing Hex-Rays has that Ghidra doesn't (and cannot) is amazing support. Back when I had a license at work, I could report bugs and literally get a fixed binary back a couple of hours later.
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 :-)
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.
Ghidra outstrips IDA Pro in the number of architectures it supports.
