Well, although working with pdf's works all right using the finder and spotlight I find that Papers does give me way more power in organizing and working with literature, similar to the the advantage iTunes has over working with music using the finder and spotlight.
One problem with spotlight and articles in pdf format is that it doesn't distinguish the different parts of an article: to spotlight the abstract, main body, title, authors and references are all the same thing. Thus, when you search for an article by a certain author, spotlight also gives you every article that has the author in its reference list. There is a wealth of metadata just based on WHERE in the pdf file a certain word is located and spotlight simply cannot use this wealth. Papers lets you sort/search/organize by title, authors, year, journal, keywords, abstract and so on. Extra power over spotlight. Combined with easy in-app pubmed searches, fullscreen viewing, grouping options, smart groups, tabs and more Papers really does wonders for working with literature for me.
Slightly off topic: writing the above made me see why i actually don't use spotlight a lot: It is just too general a solution, since each type of data has it's own relevant metadata and within a certain data type, specific apps are often way better at leveraging the unique metadata of the data-type in question. iTunes for music, iPhoto/Aperture for pics, and Papers for scientific pdf's.
