If we used NaNH2 to form an enolate like this, we'd likely get a mixture of two enolates, which would lead to a mixture of products. The selectivity of LDA in forming the less substituted enolate makes it extremely useful. Although less common, LDA can also be used for the formation of "Hoffman" products in elimination reactions.
