Unless you are planning on using some of the more advanced features or an obscene amount of processors and memory I don't think I would recommend Enterprise Edition. For me the STRONG need for those features or for the additional processor/memory.

EE isn't really faster than SE in the database engine. So if you are equating editions to performance directly I wouldn't.

Given the major cost difference I would not go to EE willy nilly without justification.
