PAGENAME can be used just fine in other templates. However, it should be used if and when the actual pagename may be changed dynamically, or if it makes sense to really mean the pagename. For example, templates are often categorized using : This allows categorizing it under its name, as opposed to "T", as well as support moving.

One of the problems in using "PAGENAME" is that if you copy paste data from one page to the next, then the information inside that paste will be warped. For example, imaging I copy paste all the tables of the Paladin Set pieces, and then paste them into the Paladin Set page, they'll all just say "Paladin Set +N"... WTF? They should have retained their original pagename title, right?

So yeah, it is really a question of "do you really mean `the exact name of the page this data is currently on`, or `Some name which currently just happens to exactly match the name of the article`"? In the former case, use. In the latter, (for the lazy :p )
