I don't have a lat machine so I want something where I can do wide pullups,chins and dips.

any other suggestions is welcome.

They're all basically the same thing. I doubt any of them has a significantly higher weight capacity than the others. Personally I'd probably give the edge to the Ironman and Spartan models only b/c the pullup bar is on the opposite side from the dip handles so you wouldn't have to do pullups in between the handles.
