I don't think those other new levels will ever be quick to beat.
They are once you maxed the main advancements. Not as quick as Hex Earth, but they are doable in 1-2 days each with an IM (either collected as one of the zillion powers on Hex Earth or with a leg IM artifact). Leg TS and Leg Army Cache are also useful but IM artifact will probably be sufficient to clear the other levels in a reasonable time. The only exception is Thirty Years War, which is by far the worst level, but also doable once you know where the large MCs are.
So, if you want to Super-Ascend as fast as possible, only playing Hex Earth (and skipping most other levels) is the way to go.
Just saying that the other new levels are not as bad if you got the right artifacts (in particular IM) and maxed AP advancements beforehand.
