Juicing with a blender is probably a better way to go as the enzymes are still beneficial, and most importantly, it helps keep you from quitting because it's easier. It's kind of like exercise, if you're routine takes too long or is too difficult you just give up after a while. It's better to stick with something for the long haul and any fruit and vegetable juice is way better than pizza and burgers.
A lot of people quit because the masticating or twin-gear juicers get them bogged down. The best centrifugal juicers for smooth juice and easy clean-up are those made by Breville. This consumer site www.best-juicer-ratings.com rates them all 4 stars or higher by many users. Unfortunately they're very expensive except for the Juice Fountain Compact, which can be gotten from Amazon for under $100.
I'd either get a Breville centrifugal-type, or go with the blender for a long-term commitment to juicing.
