My favorite PC, hands down.
Bolivar PC It just can't be beat. I probably smoke more Bolivar PCs than any other cigar.
I also enjoy Partagas PC especial.
PLPC is also good, especially after about 5 years of aging.
Though not really a PC the SCdH El Principe is also very nice, around the 5 year mark.
Can't tell you about any NC PCs, as I haven't smoked any that are still available.
But I used to love the CAO Criollo, in the smaller format.
