Web user controls:1. Easier to create 2. Limited support for consumers who use a visual design tool 3. A separate copy of the control is required in each application 4. Cannot be added to the Toolbox in Visual Studio 5. Good for static layout Web Custom Controls:1. Harder to create2. Full visual design tool support for consumers3. Only a single copy of the control is required, in the global assembly cache4. Can be added to the Toolbox in Visual Studio5. Good for dynamic layout

User control create for GUI purpose and it is form  of .ascx  and in aspx page you need to specify the src (Path) of the control.
Custom control is form of compiled form (assembly). For using this control you need to add referenct in your project. In aspx page your need to specify the Namespace and assembly name. Custom control is portable build in assembly can be used in any .Net application.
