Those are still around if you go for Assemblers with background in PC culture like NASM, YASM, MASM (still part of MSVC).

By the way Embarcaredo still has Turbo Assembler.

Now a thing of the past, but Assemblers for game consoles were also quite powerfull in their macro capabilities.

I never liked the UNIX Assembly culture, because naturally as soon as C became a thing, they became the bare minimum required to assemble the generated Assembly out of the C compiler, as another step into the compilation pipeline.

All the niceties of macro assemblers came through the other platforms, like being able to use NASM instead of the platform assembler, not even GNU AS nor clang are that great in their abilities as Assemblers beyond the basic stuff.
