Which rejuvenating laser treatment is best: Halo laser by Sciton, Deep FX, Max FX or Total FX by Lumenis?

I have deep and light wrinkling throughout my face, large pores and skin discoloration throughout. I've researched all these lasers and the outcome and I'm confused as to which is best. I've read that the Halo laser has the best downtime but my concern is which laser is most effective.
