I feel like the decompiler space is a little stuck? I mostly go with Hex-Rays out of habit and because I'm used to IDA, but I haven't really seen x64 decompiler output noticeably improve in recent releases.
A lot of my colleagues use Ghidra a lot now and complain about its decompiler regularly.
Is there any new approach in the works? Maybe something ML-based for optimization? Would be sad if Hex-Rays output is "as good as it's gonna get".
Rellic [1] implements an algorithm that generates goto-free control flows (citation in README), which would be a significant improvement against what Ghidra/IDA generates currently.
Unfortunately it looks like the maintenance state of the pieces around Rellic isn't very good, and it's quite rocket science to get it building. It doesn't have as much UI/GUI as Ghidra either so it's a bit far from accessible right now.
