I'm taking this question to refer to NC's.
As mentioned some sticks are aged before sold, Padron in particular (not sure who else does). LP and Fuente's are much better ROTT IMO, at most acclimated.
I also find that most of the "boutique" smokes just need to acclimate.

I've had a few aged (more than 2 years) smokes thanks to the generosity of a few fine Bums, but generally a nice long rest (12-18 mths). Most of the time my smokes acclimate a month or so, then they meet their death by fire.

I find that the less expensive smokes <$3, get better with at least a year on them. In particular, Obsidian, RB Genesis.
