I suggest you use whatever you know best - VB or VB.NET, since you can use both with classic asp

What is the difference between COM component and .NET components?
For a component to be called as COM compatible it must support IUnknown interface. This interface is responsible for reference counting of the component. When you compile a COM component all the information about various methods and their parameters is stored in a 'Type Library' (In case of VB type library information is embedded in the resulting EXE or DLL itself). To successfully use COM component this information must be available along with some registration information.

In contrast, .NET component are very different. The component do not itself keeps track of reference count. It's the responsibility of the CLR. Also, .NET components store all the information about the component along with the assembly itself. This information is called as MetaData. .NET components are self-contained units of functionality that do not require any registration.
