Honestly just use Ghidra. It has it's quirks but it's pretty good. And open source.
If it's good enough for the NSA it's probably good enough for recreational use.
The code is open source and has been looked at by several people over the years.
It would be quite hard for the NSA to sneak in a backdoor but it is never out of the question.
However, the risk is so extremely minuscule when compared to other alternatives since they are not even open source.
