Both are pretty difficult. The extra AR makes it more difficult for me, but I guess it could be seen as easier or harder depending on how well trained your eyes are at reading fast scroll speeds. AR 9 gives you more time (might be a placebo effect) to read the objects. Sometimes it is the case that if you need to read the objects as they are scrolling, you are already taking too much time to hit them correctly.
There are more red fruit jumps in Chaos and it is the longer map, which makes it easier to make a mistake over the course of the run. I'm not sure how the pros consider red fruits in terms of difficulty compared to awkward patterns. Some awkward patterns are more frame perfect than 99% of red fruit jumps.
Do you value hyperdash jumps as more difficult than large jumps that are not hyperdashed? Hypers can be very easy, even the very far ones. They get more difficult when you have to chain them. 1/4th hypers tend to be more precise than 1/2th.
