Hi there and welcome to the forum.
Science diet it generally always made with ingredients that most people here would regard as not something that they would feed to their dogs. For example, the top ingredients usually include corn meal, animal byproducts and animal fat. There is a lot of discussion in the forum regarding people's feelings about science diet and there is a ton of information on the interwebs regarding dog/puppy nutrition in general. This site -
http://www.dogfoodanalysis.com/ has reviews of dog foods based on ingredients and is decent for comparison purposes. Also to understand the ingredients and what they mean is very important and there is a ton of info on the web about that as well -

I feed my puppy a mix of chicken soup for the puppy lover's soul and honest kitchen "thrive" and she is doing great. My brother in law, however, feeds his dogs science diet and they don't seem to be doing too terrible so it comes down to how important you think what you feed your puppy is.
