I own both sets and have been using the 2.0 workouts but I can see myself going back to a rotation of 1.0 as well for variety. It's possible some of that may get updated in the live app since I know at least a few of the workouts have been updated there.
A few of them have spots where they do an exercise on one side and then don't follow up with the same exercise or amount of reps on the other. However, the 2.0 workouts also seem a little less polished to me. I wouldn't say the routines are decisively easier or more difficult overall but they feel a little more balanced to me in terms of the difficulty curve during a workout. To compensate for the less breaks, they seem a little easier to me in spots, less reps of some of the more difficult exercises. They also feel like they go a little faster, with less Safety Zones and more 'grab a sip of water' breaks. TLDR: It's a good workout and is great for beginners. Please let me know what you think, agree/disagree, etc.
RHC in particular is a very different routine with less emphasis on just middle ab crunch forms and more variance including things like Mountain Climbers. The DDP Yoga Review I was looking for I decided to write a review of DDP Yoga that might help someone decide if they want to give this workout a try. The 2.0 workouts do incorporate some new moves, some of which I like a lot.
