Depends on what you consider to be fruit juice. If you are referring to the store bought "juices", then its better to eat organic fruits. The supermarket "juices" are straight up poison. Filled with somewhere around 30% processed sugars and maybe 10% of plant material. Makes you think, what is in the other 60%? Nothing good. Probably some fluoridated water, additives, taste enhancers, preservatives and all other chemichal bs (poison) they put inside to make it taste better and last longer.
On the other hand, if we compare real fruit juice, which is 100% plant material, to eating the plant itself. There are no differences in health benefits. It's just a matter of; "Would you rather eat three apples or drink 2dl of apple juice?"
I enjoy drinking natural juices quite a lot, but only if they are from a reliable source. Thus, only if I know who made it, when they made it, and what fruits they used (if they were not sprayed with pesticides) will I drink the juice. I wouldn't drink a store bought juice even if you offered me money to do it.
The only juice I drink is the apple juice I make with my dad (we have a 100 year old apple tree that yields around 500l of juice every year) and the juices our neighbours make.
