EQ is not just the DSP. It's all of it - the DSP and the UI.
Take, for instance, ZynEq 10. And let's say that it's DSP is perfect. The reason why I would consider it to be less usable than the EQ I'm using in FL Studio is because ZynEq is really limited: the bands are fixed, you cannot move them around. The Q setting is global: you cannot make one band wide and the other narrow. It doesn't allow you to change the slope type or band type. There's no way to solo a band. There's no way to store a state and switch between the current state and another one, to hear the difference.
All of this reduces my accuracy and/or makes the process very difficult and slow. Regardless of whether I want to cut something out or just apply a broad fix.
That's what I am talking about when it comes to EQs.

There are two different aspects to this.
1. Things that crash are clearly no acceptable. Yet there is a lot of stuff
in the linuxaudio world that do crash or become unstable in some way or
another. It's usually due to a programmer being inexperienced in real-time
programming, or just copying some equation from a textbook or website without
really understanding it.
2. Then there is the question of what it meant by 'EQ'. For classical music
recording, if EQ is used at all it will be minimal, at most a few dB and
in wide and smooth bands. The aim is always to make things sound natural,
not to create an effect. The same is basically true for popular music, even
if EQ settings will be more pronounced and agressive.
What you seem to expect from EQ (reading your last post about Healing
Fountain) is quite different. Most EQs are not designed to completely
remove a frequency band or have very steep cutoff slopes, for the simple
reason that in 'traditional' audio (recording and mixing real physical
instruments) that is quite useless and would sound very bad.
So it could well be that you don't find what you need in Linux audio,
but that has little to do with the quality of what is available.
