Does garbage disposal horse power matter that much?

Does garbage disposal horse power matter that much? References I am in the last leg of a kitchen remodel and need to purchase a garbage disposal. And I am wondering how much of a difference horse power makes in the day to day operation of the kitchen? Has anyone here experienced the pros and cons to disposal units with different horse power? NOTE: I almost posted this question on the DIY site, but I feel it has more relevance here. Moderators, feel free to move it if you think it belongs there instead. UPDATE: We decided to go with the Waste King L-8000 Legend Series 1 Horsepower. It is really smooth and quiet. It takes up a fair amount of space under the sink however.
