i've used neither so can't accurately comment.
but look at the features and the specs, build quality, and audition both to help decide. for features, probably most important are the xovers: fixed vs variable, LP/HP on all channels, and do they suit your application. bass boots is not what i call a feature coz it's unnecessary.
both are budget amps, and IMHO, schneider probably has a better reputation than the little jaycar. but hey, i haven't researched these amps much before.
what will you be using it for (ie: what speakers/sub combo)?
