Getting an absolutely perfect colorimetric response isn't even a thing you'd want to do...
To get that you'd have to use straight contrast curves, flat contrast and so on. Changes in the contrast curve also changes color. If it's done right you don't get much hue change, but you do get a saturation change depending on how bright or dark the base color is before you apply the S-curve.
The color-checker is very good, and a high quality product. It basically has two limitations: There isn't that many unique pigments in it (they targeted a few select natural occurring colors, like two special types of foliage, human skintones and so on), and software options are kind of limited. There's also the smaller, plastic-case Passport version

The passport software is limiting the product I think. It's not very good in color results. Adobe's free ProfileEditor - that also works with the passport, as long as you accept that the passport and the original larger CC24 doesn't have the exact same colors - is quite good for what it does, but kind of convoluted and slow. The software included in X-rite's pro solutions all cost from 1000€ and up depending on configuration (but they're good!).
If you want a cheaper but still very well functioning solution, and from an end result color PoV high quality product - look at the qpcard 203.

(NB!!!!!)
I do have an interest in QPcard, since I still get licensing fees for designing the ink formulations and part of the software for them. I can honestly say that I think it's a very good product though. The packaging isn't as neat as the passport (if you choose the booklet version), but the function is great and the software is free. Doesn't have full Capture One icc support yet though, only Adobe support.
