It's extremely easy to implement so I can't think of any reason to try to emulate it some other way.
But the effect is indeed often quite subtle up to a point where it breaks down, this is just the nature of the filter and this is why it's different from other instruments.
The effect is more obvious on patches with resonance as the brute factor will eat it up quite quickly.
One of the limitations (or features, depending on how you look at it) of the Steiner-Parker filter as implemented in the Synthacon is that once resonance enters self-oscillation it becomes nearly impossible to disengage it without completely turning resonance off. It can be very touchy that way.
Yusynth may chime in on this at some point, but the S-P implementation in the Minibrute is a 'corrected' version of this filter that doesn't have this self-oscillation latching problem. The almost all-or-nothing behaviour of this filter with the feedback loop turned on, especially with the oscillator mixes overdriven seems to be making it function much like the original S-P filter implementation.
To wit, I think brute force and overdriving the oscillators is a lot like adding hot sauce to eggs: Use sparingly and less than you think you need, otherwise you mask the subtleties brought out by the right combination and end up tasting only hot sauce.
Ok, now I'm hungry...
