Custom matrices were used to exchange one kind of artifacts versus another. For example: Get a sharper image (less smoothing), but also produce more blocking artifacts. The new psychovisual improvements in x264 (namely Psy RDO and Psy Trellis) make custom matrices more or less obsolete. Thanks to Psy optimizations you can keep
much more details without the drawbacks of custom matrices. So better keep away from custom matrices, except for very special purposes. But make sure you get a recent (patched) x264 build with Psy RDO enabled. This also applies to Avidemux (you'll need a patched "libx264" file).
