Normal blenders have substantially more cleanup work involved.

But they also don't break as often. And can hold a larger capacity. And don't spill. Admittedly, the thought of cleanup has put me off the occasional late night margarita...

If you have a powerful enough blender like a Blendtec or Vitamix you can just put soap and water in it and run the blender itself to clean it.
