The Diamondback Atroz 3 has a really great spec for a full-suspension bike, especially priced at $1400. Only real compromise is that it’s a single-pivot design, which means there will be some pedal bob on the climbs. This is the reason it’s so affordable.
The Atroz 2 makes a lot of parts compromises, and is probably not such a great value for $900. A good hardtail like the Trek Roscoe line would serve you better.
I wouldn’t buy a full-suspension bike from BikesDirect. Look at used bikes on Craigslist or Facebook Marketplace for a great deal.
