What is the difference between custom controls and user controls?

Custom controls are basically compiled code, i.e., DLLs. These can be easily added to the toolbox, so it can be easily used across multiple projects using a drag-and-drop approach. These controls are comparatively hard to create. But User Controls (.ascx) are just like pages (.aspx). These are comparatively easy to create but tightly coupled with respect to User Interface and code.
