What is the best catkitten food on the market?



Ive heard so many different opinions about which cat and/or kitten food on the market is the best. Ive heard Science Diet, Iams, Sheba, Purina One, etc. To the cat experts out there - which cat food is the best as far as healthy and tasty? Also, is it better to for a one year old kitten to have soft or hard food?
