Since in this case the filter is being used to cure an audio problem as opposed to being an effect, the steeper 24db/oct slope ought to give better results.

>Thing is, despite the numbers, is there likely to be much of an audible difference between the two approaches in the average playing situation?

I expect it very much depends on the rest of your kit.
Do you play 5 string? If so, 12 db down on the B1 fundamental is going to be audible.
If you play with a lot of dirt, you will probably find that much HP filtering will clean up your tone significantly.
Even if you don't use either, you may get significant improvement in tone if your amp and/or cab(s) are struggling.

In most cases 24dB/octave is going to be much better if what you want to do is clean out the crap without affecting your sound.

Happy to give you the technical reasons if you want.
