Office 2007 Ultimate Edition is obviously the best suite available. It packs the most apps, and being the latest edition makes use of cutting edge technology.
Enterprise and Professional Plus editions are close runners-up, but can only be purchased through volume licensing if i recall correctly. Ultimate is available on retail...over the counter yada yada yada
Thats the answer to your question.
