Chocolate pocky, meh tier. Not worst, not great, formulations might have changed over the years.
Green tea pocky, garbage tier. Other brands are actually good, pocky however can't make a decent green tea for some reason.
Strawberry pocky, pretty good tier.
Rarer versions, depends, most of them are just novelty flavored.
Mens Pocky. Only /am/ine pros can buy these. Shops will card you when you try to buy it. Shops who don't, are selling you counterfeit contraband.
