In response to those saying they would rather have more horsepower, and less torque, here is a decent article I found explaining the difference between the two. The peak horsepower really means very little if you don't have enough torque to take advantage of the power.
Notice that although Engine B has more peak horsepower, Engine A has more power at speeds up to 5500 rpm. What's more, it has significantly more power in the 1500-4000 rpm range (highlighted area), the range of engine speeds in which you'd typically operate a car.

Now let's look at the torque curves of the two engines:

We see that Engine A puts out much greater torque, especially over the typical engine speed range, indicating that under normal conditions Engine A will give you much more “oomph” than Engine B. Peak numbers are nice to brag about but often don't mean much, since few people operate their engines at peak conditions (which would generally be full throttle) in a typical day.
