Well, 'best' in this case should be determined by combining a number of factors. Certainly technological superiority should be weighted quite heavily, but in certain circumstances the "Nobody ever got fired for buying IBM" effect is also very important.

Of course there is also the "The best tool for the job is the one you have/know." quip, which I don't generally agree with myself... so I guess what I'm saying is that your mileage may vary.
