Frankly to say, i have big criticism for Iris 2 lol, but would not want to go into details, for the sake of politeness.
Can only say that if Iris can be compared with Abyss (and even more so with Pigments), then only in genre orientation (or rather, application for).
On the technical side, things are not only different (as was rightly noted above), but also of different levels of complexity (and not in favor of Iris). That I wouldn't compare them at all.
