I know nothing of Durango
One summer, I spent a month riding in Durango, and then I drove to Cortez, and I spent a month riding Phil's World and Bogey Draw on alternate days, and I explored all the trails. I don't think Phil's World is that great, and I thought the trail Rib Cage was pretty lame. It didn't have much flow for me, and I couldn't get air on it, so I thought it was a poorly designed trail--or maybe I just wasn't a good enough rider to appreciate the trail.
I preferred the Bogey Draw system. It's at a higher elevation than Phil's, so it was cooler, and it was more scenic. I camped in that area, and I got showers at the rec center in Cortez.
As for Durango, it's pretty intimidating. High elevation, lots of 5+ hour rides, and it's easy to get lost and get in serious trouble, and every trail starts with a brutal climb. There's very little tech in Durango, but if you seek it out you can find it, e.g. Snake Charmer, Raiders Ridge (I got caught in a lighting storm on Raiders Ridge, and I feel lucky to be alive!) My favorite loop was starting at the Dry Fork trailhead and climbing up to High Point on the Colorado Trail, then turning around and descending the Colorado Trail to Hoffheins. Hoffheins had some little drops and some short rougher sections, which I enjoyed.
I got up into the Durango High Country once. I had planned on doing a no-possibility-of-getting-lost out and back ride, but I met some locals as we leap frogged each other up the climb, and they invited me to follow them on a loop, then they offered to shuttle me back up to my car after the descent dumped us out on the highway. I still had some legs, so I declined and I climbed back up the highway to my car. A memorable ride for me.
There are many breweries in Durango, which can be accessed from the various trails, and the public library in Durango is spectacular. It has balconies with deck chairs that look out over the sparkling Animas River, and I'll never forget sitting in a deck chair and gazing up at the azure blue skies and watching brilliant white clouds form in the afternoons.
