You're definitely right, Droless. NNTA is incomparable, the absolute masterpiece, even though I also love EEIDISWCW, because it represents the original, pure spirit of the Cranberries: the beauty of a simplicity that never turns into banality, powerful rhythmics, beautiful melodies, all stick together by that unique voice.
Obviously it's terribly difficult to be simple and original at the same time, and it's even more difficult to remain, so simple and original. That's why I think WUASTC was not a good work: there are a few very good songs in it, of course (I like This Is The Day, I Really Hope, Chocolate Brown), but there are some mediocre ones too (Time Is Ticking Out is maybe the worst Cranberries' song, I still can't believe that it was even chosen as a single!).
If we look at the results of the poll about the best album, we can see that many fans agree with you and me, Droless (by the way, is this your real name?). More than half the forum members consider NNTA the best album (it's easy to recognize a masterpiece), while WUASTC is the only album without a single vote.
