Would you rather play Omar Vizquel or Albert Pujols at shortstop?

Let's say you can sign one free agent for your baseball team, but for some reason you must play that player at shortstop.
You can either choose a player who is one of the top five hitters in the majors but has basically no fielding skills (e.g. Albert Pujols), or an amazing defensive shortstop who is basically an average hitter for his position (e.g. Omar Vizquel). Assume the costs are equal.
Who do you choose and how do you make this decision?
