Which exotic architectures is IDA missing from your perspective?

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.
