Suggest you smell the punnet and test for fragrance. In my experience, the fragrant ones are the tastiest. (Covered punnets obviously, but the plastic film usually has tiny holes which lets the fragrance diffuse out. You don't need to get too close, and they should be washed before eating.)
Don't eat them straight out of the fridge either. That kills flavour.
