Binary ninja is another good option. In my experience it's pretty similar to ida but I find it more user friendly. It just has a lot of well thought out features that make me more productive. I haven't tried hopper but ghidra and radare2 both had a bad dev experience and produced c that didn't "read well". Granted it's been a couple of years since I tried either.
Binja is $300 (or $1500 for commercial, both cheaper for students).
Our view is: the engine is 100% open source. The UI is available for free in the cloud for anyone experimenting, which we define as "I'm OK with leaving the project public".
Basically, the decompiler engine is Free Software, extensible and available for automation/scripting, while the UI is available for free for students/researchers and we can make a living out of professionals (i.e., when your company is paying for it).
Oh that is awesome!
I've used the cloud version previously but now that the desktop version is free with some small limitations i think I'll probably use it instead of Ghidra
