According to customer reviews, the Omega juicer does a slower job of producing juices, and will take around 45 seconds (excluding preparation and setup) to yield a 12-ounce glass of fruit or vegetable juice. The Champion is much better in terms of speed, and can yield a glass of juice in a matter of seconds. If you need to make big batches of juice in a short space of time, the Champion is best for you. However, none of these juicers are exceedingly slow.
