Which Driving Academy is harder?

[gagar]

Finally managed to complete both ETS2 and ATS academies with 3 stars.

I understand, that the complexity is supposed to be around the same, however I noticed before that for me ATS was in general simpler than ETS2 (wouldn't say it was not challenging though). Maybe it has something with the fact that I finished ETS2 first. But Twisted exercise in ATS just confirmed my thoughts on that: in ATS I was able to master it in 2 hours, while ETS2 version took me few weeks.

So, I wonder, what others think about that? Let's cover only Part 2 for clarity, given that it is supposed to be harder than Part 1 and also people should have fresher memories about it.
