I moved from 6502 assembly to PowerPC assembly. I found 6502 assembly easy to understand because of the limited number of registers, instructions and addressing modes. You didn't have to learn very many. And as it turned out, I didn't have any problems adapting to the expanded PPC ISA. Being on the 6502 already taught me how to chop problems down into tiny bits and now the bits didn't have to be so tiny. I certainly wasn't trying to do 8-bit chained adds for bigger quantities anymore; it didn't make sense to when I had 32-bit registers and an FPU.
