Norton safe search and Google question

My computer was updated from NIS 2010 to 2011 yesterday.

 

An alert box appeared asking if I wanted Norton safe search activated.  I unckecked the okay box.

 

I've been using Google for all my searches, but now I'm wondering if I should use Norton Safe Search instead.

 

My question:  Is it better to use Norton safe search?  Are there advantages to using Norton's, instead of Google?  Or it doesn't matter which I use, just a matter of preference since the results are the same?

 

Thank you.
