Stuff I've recently analyzed that IDA has no decomp support for (and Ghidra's is anywhere from good enough to actually good):

  - AVR
  - Z80
  - HC08
  - 8051
  - Tricore
  - Xtensa
  - WebAssembly
  - Apple/Samsung S5L87xx NAND controller command sequencer VLIW (custom SLEIGH)

And probably more that I've forgotten.

It's also not about lack of support, but the fact that you have to pay extra for every single decompiler. This sucks if you're analyzing a wide variety of targets because of the kind of work you do.

IDA also struggles with disasm for Harvard architectures which tend to make up a bulk of what I analyze - it's all faked around synthetic relocations. Ghidra has native support for multiple address spaces.

Binary Ninja supports some of them as well, highly recommend.

		I really want to like Binary Ninja, but whenever I have the choice between not paying (Ghidra), paying for something that I know works (IDA) and paying for something that I don't know if it works (Binja) then the last option has always lost so far. Maybe we need to get some good cracked^Wcommunity releases of Binja so that we can all test it as thoroughly as IDA. The limited free version doesn't cut it unfortunately - if I can't test it on what I actually want to use it for, it's not a good test. (also it doesn't have collaborative analysis in anything but the 'call us' enterprise plan)
