Agreed about Isis' randomness, but part of what makes Oceanic and Panopticon so engrossing is how the music expands on itself and wanders in different directions, only to resolve brilliantly in many cases. All part of their overall atmosphere. I find Pelican more focused and heavier (not taking the new one into consideration), but they don't have the same depth, although much of Australasia does approach and even surpass Isis for sheer intensity.
