I'd guess that 8051 is the easiest. I suspect that a huge percent of 8051 is still hand-coded assembly. It has an accumulator architecture and the instructions were made with hand-coding in mind (plus, there's not very many of them). I remember it being pretty easy to learn, but that was a long time ago. To me, RISC assembly tends to be quite a bit more complicated to write by hand. https://www.slideshare.net/Andriblovers/8051-instruction-set-12522439 https://www.slideshare.net/Andriblovers/8051-instruction-set...
