aptitude is, generally speaking, a more user-friendly interface to the 
apt system. If you're scripting (and especially as it already works), 
you should stick with apt-get. apt-get's output tends to be more stable 
and more readily parsable.

Is there some feature of aptitude that apt is missing? What's your 
motivation for switching to aptitude here?
