Got all these 4 types of toothpaste for my kids mainly because of the kiddy and attractive packaging . It comes with Mickey Mouse and friends, Winnie the Pooh, Buzz Lightyear and the Disney Princesses. For the first two types it comes in a mild fruity bubblegum flavour. For the buzz lightyears it has Fruit Blast flavor and the princesses type has pink bubblegum flavour. My kids had tried all the four types and they like the Buzz lightyear fruit blast flavor best . The other thing that really attract me and my kids is the unique squeeze bottle and my kids love to squeeze those unique fun shapes so brushing teeth becomes an enjoyable chores for them . About effectiveness, so far they do not have any cavities yet and they do have strong and white teeth.
