What is the best food/nutrition tracking app for either iPhone or Android phones?

The apps I like for the iphone are SparkPeople, My Fitness Pal, Fooducate, and Nike Training. Those are the ones I am using right now and I really like them.

Fooducate is really cool because you can scan food item bar codes and they get a rating and they also give a healthier option to the item that was scanned!
