Beware of the CDP1802. It's been long enough that I don't remember the
exact causes, but in order to CALL/RETURN something you had to
execute an inordinate number of instructions. I hated it.

I liked the 8085 for real time stuff (good self-contained interrupt
structure). The z80 for mixed lang programming. But the 6800 and
up were plain elegant and easiest to code. A highly orthogonal
instruction set. I am still somewhat of an expert in 68hc11 programming :-) .

The 6502 and the X,Y pointer mechanism, though good for graphics,
I never liked entirely...

I could comment on something other than 8-bitters, such as DSPs or
a couple 32bit uproc's, but that would be too long.
