The Steeda's are far and away the best deal, if you plan on doing any kind of road racing or autocrossing. I have the Ford Racing ones, that I had boxed in and 'performance coated' (read: expensive chassis paint, lol) I only went with them, because they were a package deal. If I were to buy a set outright, it would be the Steeda's.
If you plan on doing any drag racing, then by all means, go with the stiffest set of adjustable arms you can get. They are all pretty good, stick with a tubular arm, with the stiffest polyurethan you can get.
