I just did another quick test after I bounced a demo and noticed that it suffered from the same issue as everything I use EZ on.
Using two supposedly similar retro kits, one in Kontakt and one in EZ, both as flat as possible, I captured this EQ curve with Logic's Match EQ. It shows the kind of EQ'ing required to get the Toontrack drums to sound closer to the (imho) relatively more natural sounding NI drums.
Hence the scooped sound.
Pretty radical differences. And that's only the frequency domain. The dynamics are also incredibly different.
