What is the difference between Berries and Hua Language?

There's a brief comparison of both the schools and Tien Hsia here: http://ourlittlesmarties.com/2012/05/chinese-enrichment-class/ My friend sends her son to Berries. They don't speak Chinese at home but have found that he has found an interest in Chinese.

Berries World is leaning towards learn through play and songs. They provides sound chart and story reader books each term. For younger kids, Berries is a fun way to learn chinese. When your kid is older, Hua Language and Tien Hsia are more academic driven.

thanks
