Hello, the answer is No, Both the companies are different as Cadbury is merged and owned by John and Jacob and the merger is known as Cadbury Schweppes. Nestle is a Swiss company where nestle company products make more focus on people relations than systems. In contrast, Cadbury is known for its unique flavour. If you will ask me which one is better my personal choice is Nestle.
