I could see a juiced fruit be easier than whole/crushed fruit in the way of racking losses and such. But the two products will be different. Like for instance in pyments using grapes. With juice it is good to add tannin to compliment the flavors but if you ferment on the grape skins you get all the tannin you need from the fruit.
With most melomels and wine where I just use fruit I find myself adding some earl grey tea to most batches. I feel like that rounds out the batches to include what is lost when not using whole fruit. Then again not all fruited need something like that, like apples, lemon, orange...
