Not much has changed, except there are more entrants. Binary Ninja, Ghidra, radare (last two being open source). For debugging, there's x64dbg. Some use windbg and gdb (for non windows os), but it still is mostly IDA as king though the others are catching up.
I evaluated entering the space by building something with AI native however, the business case just didn't make sense
I tried Ghidra recently and the decompilation seemed decent enough. The UI seemed a bit less complete than IDA's though (I couldn't see a couple of things that IDA does/has though they might just be hidden away in menus).
