If, when you are 80 years old, you care which MBA you took, then you have wasted your time on this planet.That said, go for the best MBA you can, relative to what you personally want out of it (intellectual stretch, personal networking, career switch to specific industry, move internationally, improve your salary, start your own business, etc.). The FT and other rankings have sub-rankings by these and other subjects/career objectives. If cost is a significant factor, look at the value-for-money/ROI columns of the various rankings.
