Web User Controls:
1) Easy to Create
2) Limited support for consumers who use visual design tool
3) A seperate copy of the control is required in each
application.
4)Cannot be added to toolbox in Visual Studio.
5) Good for Static Layout
Web Custom Controls:
1) Harder to Create
2) Full support for consumers
3) Only a single copy of the control is required in the GAC

What are the basic differences between user controls and custom controls?
Now that you have a basic idea of what user controls and custom controls are and how to create them, let's take a quick look at the differences between the two.
Factors User control Custom control
Deployment Designed for single-application scenarios
Deployed in the source form (.ascx) along with the source code of the application
If the same control needs to be used in more than one application, it introduces redundancy and maintenance problems Designed so that it can be used by more than one application
Deployed either in the application's Bin directory or in the global assembly cache
Distributed easily and without problems associated with redundancy and maintenance
Creation Creation is similar to the way Web Forms pages are created; well-suited for rapid application development (RAD) Writing involves lots of code because there is no designer support
Content A much better choice when you need static content within a fixed layout, for example, when you make headers and footers More suited for when an application requires dynamic content to be displayed; can be reused across an application, for example, for a data bound table control with dynamic rows
Design Writing doesn't require much application designing because they are authored at design time and mostly contain static data Writing from scratch requires a good understanding of the control's life cycle and the order in which events execute, which is normally taken care of in user controls

What is the difference between User Control and Custom Control
Custom controls are compiled code(Dlls) easier to
use,difficult to create and can be place in toolbox. You can
drag and drop controls, Attributes of this control are
visually set at design time. A custom control can be used in
multiple application as shared DLLS. Any one can copy DLL of
custom control in bin directory and add reference and use
them. Normally custom controls are designed to provide
custom functionality independent of consuming application.
User controls are similar to those of asp include files easy
to create, can not be placed into the toolbox and dragged
dropped from it. A User controls can share single
application files. Normally designed to provided
functionality that is reusable for the particular application.

Answer / nitin
Web User Control inherits .NET class i.e
System.web.UI.UserControl
whereas web custom control does not do so.
