Price and ease, the GM conversion will still win.
Leeds (Leads?) has a new kit out with a bigger rotor off a Dodge and late model F150 calipers that is worth looking at.
Wilwood still has new stuff that they are proud of, I feel pointless in the small rotor department, but worth a look if you want big rotors and have deep pockets.
Duff still has the Ford knuckle clone option they have had for decades.
With todays market, I would look at the Leeds kit, with the GM stuff as default backup.
