I don't know, it depends on the look you are going for. The previous cliff looked more natural to me. The new one is definitely pleasing to look at though (with very nice clusters). The new cliff is less busy too, which is probably better for a game. Although the new boulders maybe don't seem to "support" the grass as much as in the old version at the top of the cliff.
I really like the new transition between the bottom of the cliff and the grass.
