Blog Statistics - Blogger and Google Analytics - Which is Correct?

Since I started Bruce's Journal in October 2005, I have been curious how many times this blog has been accessed and who is reading it.  I can also find out which entries are hit more than others.  For many years I have used Blogger provided and Google Analytics to get statistics.  The values of the two services have varied greatly with the former giving higher numbers.  The latter gives the city of the user but did not include my hits last week from Houston.  It will never reveal the name of the person or the IP address.  There is someone from Monroe Township, NJ who has accessed my journal for years, but I don't know who he/she is.  In general, the number of hits for recent entries are higher, but I have some classic posts.  A high percentage of my readers are from New York and New Jersey, but I get readers from all over the world.

My question is which service gives the correct data?
