I think most people that like Nicaraguan cigars like that big pepper blast they find in them. And aging tends to take that away. Padron is unique in the fact that they aged the tobacco for years with the Anniversary cigars then roll the cigars with no additional aging needed. So an Anniversary Padron is usually best fresh out of the box, where the traditional line can benefit with some age.
Personally, I like the pepper blast to settle a bit with the full bodied Nicaraguan cigars, so I like to give them some downtime. I love some Tatuaje Cazadores around the 3 year mark, but my problem is the box rarely makes it 6 months.
It all comes down to personal preference anyway. If you want a full bodied Nicaraguan cigar at it's strongest, most peppery and full of nicotine, smoke em fresh. If you prefer it a little more toned down and want to enjoy the subtleties the cigar has to offer, then give it a year or two.
