Is it good to use the ATL COM wizard

Absolutely. The ATL will give you no perform hit what-so-ever (no more than the COM overhead anyway)

If you want need/want language independence nor need/want threading-model independence don''t use COM. Learning how COM works is still a decent idea, as it is a pretty good OO design to accomplish it''s goals.

I have yet to seriously use .Net so I can''t make any reliable statements about how it truely compares to COM. It sounds like a better/easier/more integrated solution (but it offers no additional capibilities - COM and .Net objects are inter-exchangable).
