Also from their website:
A warped curve corresponds to standard digital filters, a decramped curve to Orfanidis filters, and an analog like curve is very close to the analog reference curve.



Several digital EQs have decramped bell curves (standard Orfanidis curves), but most of them have warped Low Pass and Shelf curves. That is probably because many EQs of the market are based on exactly the same algorithms.

We do not say that one EQ is better or worse than another, or that one will sound better than another. This chart just compares the technical characteristics of some plugin EQs. Using one EQ or another is also a matter of taste.

An analog like Low Pass curve is very important to have a smooth high cut. With a warped curve, the more you get close from the Nyquist frequency (22.5kHz for 44.1 sampling frequency), the more the Low Pass cut is sharp. It is impossible to get a gentle cut at all frequencies with such Low Pass characteristics.
