I'd go with Ghidra, but I might want to add, or I'm unsure if you don't know this, but decompiling won't obviously give you the original source code of what the developer wrote. It will give you intermediate pseudocode. For CSGO, you can find a lot of SDK headers online, which you could import as type libraries to increase readability for said pseudocode.
Yes im aware that it won't produce the source code, would you mind linking the sdk headers?
I personally have no idea where to get them, but you could just look around or use the csgosdk for it.
