Pretty sure Badlands and Black Diamond Sasquatch are intended for a higher degree of difficulty trails. More steel where you need it.
Depends on how you look at it, from the showroom floor (and I'm specifically targeting 21-22 stock broncos): The FE was a fully decked Badlands, Lux package, stabilizer disconnect and Sas were standard options and the goat modes included rock crawl. The downgrade to that was the Badlands, where you had to buy the sas and high/lux upgrades but it came with the same bash plates, modular bumper and rock rails. The downgrade to that was the black diamond which also included the plates, bumper and rails as standard.
Enter the Wildtrack which included a sport mode instead of rock crawl, it included sasquatch and front/rear lockers but bash plates and modular bumpers were options along with high/lux. Downgrade that to the OBX, no front lockers unless you add sas, sport mode instead of rock crawl, you had to upgrade to the modular bumper to get a front end bash plate, it came with tube steps instead of rock rails and it's the first model with 6, not 7 goat modes (baja mode left the building). Downgrade that to the Big Bend where it maxes out at mid package. Tube steps, sasquatch, modular bumper and a front end bash plate are all add-ons...there's a reason why this is now the lowest Bronco on the food chain and it's because it comes with the least amount of "standard" options (or forced expenses, depending on your outlook).
In 2020 when specs were being released, these were the comments: Looks like the OBX is the mall crawler and the Wildtrack is the advanced mall crawler while the Badlands was the rocky mountain mall crawler and the FE was the luxury rocky mountain mall crawler. It was also noted, in the Toyota Tacoma world, the Wildtrack and OBX would be considered TRD Sport 😂
So yeah, right off the showroom floor, the badlands and black diamond were intended for higher difficulty trails, but as skid plates/rock rails, lift kids, etc become easier to get for all the bronco variations and with the addition of the hoss 3 system that "intention" has changed from the initial concept of "if you want to rock crawl, these are your 2-3 options" to now it's basically, "buy what you like, we make a part for that"
