I have a both sets of Pantone plastic chips (old binders and new spindles).
The new PQ versions share the same number as the ink formula versions, and they kinda match. But the reality is plastic color appearance varies drastically based on the lighting conditions, you can hold the same Pantone number ink swatch next to it and it might appear to match it 30% of the time as you look at it from different angles.
The chips themselves aren’t uniformly darker or lighter to their ink counter-part, every color will be slightly different. Even if you order multiples of the same plastic chip, if they are from different production dates, their color might be slightly different as well. Honestly the real advantage to the plastic set is being able to see what a plastic color looks like, sending it to a plastic house, and have them make their plastic pretty close the sample you provided (much closer than a paper/ink swatch would). The fact they made the plastic chips somewhat match the ink formulas is a great bonus (though they aren’t a perfect match all the time)
