Is Fritz Full Analysis or Blunder Check better?

I now have Fritz 10. It will analyze your games for you. There are two
types of analysis: Full Analysis and Blunder Check.

Neither are perfect. For example, say in a position there are two
choices: One is to win more material in a complex position. The other
is to trade queens and enter an elementary won endgame.

The human player will trade queens. Fritz 10 will recommend winning
extra material.

Here is a game I recently discovered from the 1966 US Open in Seattle.
I must thank John Donaldson for providing this game. He found it in an
old tournament bulletin which feature my game as the most interesting
game of the round. I had forgotten all about this game, but it is
truly an interesting game. I do not know whether I sacrificed a piece
in the opening or simply blundered it. (I think I blundered it). But,
I got three pawns and won the game by threatening to queen.

As I am writing a book on the US Open in Seattle, I must decide
whether to use Blunder Check or Full Analysis or possibly to not use
Fritz at all. I would like your opinions as to which to use.

Here are the games analyzed both ways. Please send me your opinions.
First is Full analysis.
