Fresh fruit is better as the syrup is going to be bad for them. Fruit is already sweet, without syrup.
Ideally, fruit is given less often than veg, as it's better for your budgies. I found just trying different things and presenting them differently eventually paid off. Mine didn't like things in a food pot, chopped up or hung up, but just on the floor of the cage, as is (example, spinach leaves as they are). But just keep trying. They can't eat it if it's not there.
(but don't give them the syrup stuff)
