A 31 band gives you more options (frequencies). It may be too much. That is good if it is. You should never want to have to boost or cut many bands. Less is better ideally.

A parametric EQ in a soundcard may be ok. It may not. It could be more precise, meaning you can dial in a specific frequency and then narrow the bell to notch out feedback. If your computer has a spectrum analysis plug-in, then you might look at that, and then dial it out with the parametric. Parametrics can get people into trouble.

What a feedback eliminator does is look for peaks. You set your mixer up with unity gain. You then push your master fader up until things start to ring. Then the processors will start to knock those f's out. Some of them will have parameters allowing you to set the width of the notch. Eventually everything can ring. So you have to know when to stop. Most units rotate filters. So you can run out. You never should to begin with. But, unless you are using these is a commercial install with no technical support, these are a very big waste of money. That said. The Feedback Ferret by Peavey is probably one of the best bangs for the buck.
