PAN's are good, but the PAM's are defiantely better. Looking at the two side by side its almost a little hard to pickout the maduro, as its not your typical dark cigar. However you will notice cedar and a leathery body when you smoke the maduro. Very smooth, and even better with a couple years of age on it.

I've smoked a ton (well, many) Padron 26's as well, and still personally enjoy the 64's better.
