ASP. NET? Or JSP?

Today, a friend asked me whether ASP/ASP. NET is good or JSP is good if he wants to learn website Script Programming? I heard that ASP scripts are inefficient. In my opinion, ASP is interpreted and executed in the past, and the execution efficiency is relatively slow.

NET is that it can CodeSeparated from the content, the artist can work independently to make the site design very beautiful. Now Asp.net uses Web Control and does not distinguish between client and server programs. This is a great improvement.
