I've also found Ghidra nearly useless for most things. IDA seems to blow it out of the water. I've also had significantly more success with OOAnalyzer but as you say, it's dog slow and just consumes an unfathomable amount of memory. I had a few binaries it just completely choked on regardless of part size. Finally, while Ghidra is pretty cool in theory, in practice it's quite brittle and rough at the edges. I've had projects get corrupted, analysis that always hang indefinitely with no diagnostic information why. And it performs about the same on a 4-core host as a 64-core host, which deeply saddens me, as almost nothing is multithreaded.
