In my area probably "Bacteriophage" or "RNA interference" are best, as to the worst, probably "Metabolism", which is little more than a C-class article (covering only a fraction of this topic and citing only 5 references).
The article on "NMR spectroscopy" is good, but probably too technical.
That's the problem with production of wikis - there's no real interaction with readers, technical or not. On Wikipedia, the level expected of the reader varies from complete moron to PhD mathematician (although usually its the former).
Sometimes this effect happens in a single article.
