While I don't really use alignments much, I'd have to say that my previous campaign (Dark Sun based, and quite long lasting) was NG, CN, N, N, N, N, LN, LN, NE, LE (there were a few more, but they were infrequent guests). Pretty much a centered group, with derailments thrown in from the LE and NG characters. The neutrals had the predominant voice in the long term while the lawfuls kept the party in line with pragmaticism. The NG character was the voice of morality, much to everyone's dismay, while the LE was the voice of 'the ends justify the means'.
Current party is much smaller with CG, N, LN, LN, NG (again in Dark Sun), but in general, the party leans towards lawful good in its actions, decisions, and long term outlook.
Personally, I like playing LN if coerced into a strict alignment.
