The reason why nobody agrees is because tires are subjective actually. The performance of the tire vastly depends on the vehicle it's on as well. Very few people have actually ran many different tires before ON THE SAME VEHICLE. Most people find one tire that does, or what they think does...
The First Edition is in all honesty just a Badlands... The only actual difference is cosmetic, comes with the leather interior standard and the gloss black grill, mirror caps, and wheels included on the WT.
70k seems reasonable. I suspect they will undercut Jeep a little and can justify it since it's going to have the 3.0 ecoboost and not a V8. A First Edition is priced at 65k so it would likely have all the same options since it's going to be the high tier flagship Bronco so $5k more than the FE...
