The advantages of both EQs:
The Sutie Effect EQ
- comes with a huge amount of presets for vienna instruments
- max Q = 10
- has a very low CPU consumption, nevertheless it sounds transparent
- good for general tasks in each track (low cut, some instrument corrections)
The Fabfilter EQ
- comes with some general presets
- has a low - high* CPU consumption
- *also can be used in linear mode (more than one)
- very high Qs are possible (Q = 40)
- M/S treatments
- very flexible in using different filters
- a lot of filters are possible per unit (24)
- very good for sound corrections tasks in each track (low cut, some instrument corrections)
- very good for mastering (linear mode)
- very neutral sound (not warm, no analog/passiv sound - simply neutral)
I use both: In each track a VSL EQ for low cutting and easy track corrections.
In sums or when I need more complicated corrections (also M/S) I use Fabfilter.
For musical sound corrections (more warmth etc.) I use neither VSL nor FAB-Filter.
I have to mention that I never use VSL-EQs with my real recordings because I feel that they take away a bit the warmth of the recorded music.
I only use the FabfilterEQ and musically EQs. Keep in mind that there are EQs which cost the price of the whole SUITE EFFECTS.
This doesn't mean that the VSL-EQs are bad. No, that means "the right tool for the right task".
So the question "VSL or Fabfilter?" can be answerd by: Buy both, because both of them have their advantages.
