I'd kinda say that Judgement and WHBWH are equally fantastic, I'd say that WHBWH probably has the higher highs (or more highs) with songs like Universal, Hindsight and Thin Air, though Judgement is more solid all the way through.
WHBWH does have a few minor issues for me, Everything's chorus being slightly too repetitive and annoying at times, and even though Dreaming Light is great, I feel like Anathema has made better songs in the same vein as that one.
So yeah, would rank them pretty much equally great.
