Ghidra is as good as IDA with caveats, in my opinion. If you're reversing a less-common architecture (not ARM/x86) which Ghidra supports well, it's much more effective than IDA simply by virtue of having a psuedocode decompiler (IDA's Hex-Rays is architecture-specialized). The IDA GUI and scripting functionalities are much more common in tutorials and the ecosystem, so the Ghidra learning curve can be greater, but it's not really inferior. IDA has fewer decompilation/disassembly bugs but in both IDA and Ghidra, bugs are usually fairly easy to spot and not a huge detriment to achieving a goal. IDA deals with C++ better than Ghidra (imo). Anyway, for free Ghidra eats IDA's lunch, and the IDA home edition offering is weak - so for a hobbyist, Ghidra is a clear home run.
