As a grail, I’ll vote for the 5004 or 5204, due to the complication and balanced esthetics.
Now if we are talking about PPC’s , my favorite will be the 3970P silver/white dial followed by the 5270G first generation closely followed by the second gen(chin), all others are okay, but in the case of the 5970 the date display dial cutting in the minute track and omitting the 28-32minute markers always bothered me and I just can’t make peace with that.
At this level, I personally consider that little “imperfection” as a design flaw…
But to each his own…🥂
