I was lucky, in the sense that I jumped from Z80 to 386/486/etc. Because Zilog was basically founded by ex-Intel staff the instruction-sets weren't too dissimilar. I could never get my head round 6502-instructions (as a teenager). These days I guess my knowledge is largely obsolete as I stopped writing Intel assembly language around the time SSE came out. Still there are times when I decompile & patch binaries for fun, so it wasn't entirely wasted.
