That feels like one of these misleading marketing statements. The real competition are GCC and clang.
But yes, embedded compilers are usually a nightmare.

Yeah, I get that with embedded, it's a crapshoot. However it's probably not ridiculous to say that GCC ports to microcontrollers is not terribly uncommon, either.
GCC and Clang certainly are a lot more useful than for just that tiny range you listed. The reality is they probably cover more platforms than any other individual compiler.
