In terms of vitamins, they might be just as effective. However, this sweetness means that they have sugar added, and you don't want that. So you can just get a multivitamin that has nothing bu the vitamins, such as Ruthless 3D.
The vitamins are equally effective but you are getting a bunch of sugar along with the vitamins which obviously you don't want. It's almost like taking something to improve your health and wreck your health at the same time. Seems sort of counterproductive to me.
Just get a regular multivitamin in pills. Don't fix what isn't broken.
