Edge models have: Cloth & Vinyl seats unique to Edge models, color matched and smoothed front and rear bumpers, color matched and smoothed flares(if styleside), plastic/vinyl flooring instead of carpeting, all Edges(even 2wd) have the same raised 'powerdome' hood as the XLT 4x4's as well as the same grille and same style bumper with fogs. The non-power optioned trucks have basic door panels that are carried over from the XL models. XLT's w/o power options got nicer door panels iwth map pockets. And, as far as I know, the 2wd edges all came with torsion bar suspensions, which made lowering them more difficult.
Ford has the Edge model as one step down of XLT, one step up from XL. But in all reality, they are basically the same truck...they can be equipped the exact same options as an XLT.
