Speaking of decompilers, would Binary Ninja be a safe bet to pick? I've been told IDA is the gold standard, but it's also expensive for someone who wants to recreationally reverse engineer.
Though for me the big selling point on Binja is the Intermediate Languages (ILs). HIgh-level IL is the decompiler but you also get Low-level and Medium-level ILs as steps between assembly and source. If the decompiler is a bit funky you can look at the ILs to get a better idea of what is happening. the ILs are also just much nicer to read than plain assembly so I tend to use them a lot.
Its a feature that isn't really matched on any other platform. Ghidra and IDA both have a single IL that is more machine readable compared to Binja's human-readable ones.

The only thing you lose out on is Python scripting, which is kind of big, but for a free tool you really can't complain.
You probably want to use both IDA and Ghidra since they have different strengths/weaknesses and community plugins.
