I personally believe that it is better if some of your roll resistance comes from an antirollbar rather than relying solely on the springs as you end up having to have harder springs to compensate for the lack of an antirollbar.
So I would be inclined to only go with compression struts if using an antirollbar too, but lots of people have done it without and will tell you that it handles great etc, but I suspect they have never tried a truely well setup antirollbar based setup if they beleive that the antirollbar can bring nothing at all to the party to improve handling!
