Adaptive Optics vs Space telescopes

With the curent technoglogy of filters and adaptive optics, as well as being able to use multiple mirrors in an array for ground based Telescopes. Do we really need space based telescopes like hubble, oreven newer ones? Granted some things like Ultra-viloet telescopes can only be done in space. But if you could only choose betwween a space telescope, or a Ground based telescope which would it be?
