If you ate the fruit it would be much better for you. Instead you are basically taking something healthy overall, extracting the candy part out, and throwing away the parts that are best for you.
I'd bet that eating the fruit & vegetables would be better. But at this point, neither my wife or I will be eating kale or celery for breakfast. Juicing helps us at least some vegetables in our diet. Baby steps.
Eating fruit is better than drinking fresh fruit juice, which is better than drinking Mountain Dew.
The problem is that people think fruit juice is healthy and nutritious, and they aren't aware they should limit consumption.
