My favorite CPU was the 8088 that was in my first personal computer. I had a TI before that, but that was really a game system more than a useful computer.
I played on that 8088 for hours every day, even though I didn't have any games for it. I spent that time playing with GW-BASIC and I wrote my own games. It was fun figuring out how to move sprites around, and create the scenes I had envisioned in my head.
Of course the first will always be the one I have the fondest memories of, but my current CPU seems to do just fine as well
