With the caveat that I've only had 2 sessions, only climbed on the more repeated benchmarks, and not tried anything above 7A, I would say...
Slightly.
The 6s feel fairly similar I think, once you've got familiar with the new holds. The 7A's I've tried are on average a bit easier, I've flashed one and I've never done that on any other moonboard set. Didn't feel miles out compared to the low 7's bouldering I did in N Wales a couple of weeks ago.
For context I'm not great on a board normally, but the feet follow/small box style of the moonboard suits me better than the tension of a normal woody.
