I would say your best bet would be to scour Cisco's website on each part and see the differences. For instance, there are some functions that a MSFC2/PFC2 can do that an MSFC1/PFC1 can't do. (AFAIK) you HAVE to have a Sup 2 to support a MSFC2/PFC2, but you can run an MSFC1/PFC2 on either a Sup1 or Sup2. If you look on Cisco's website for "Supervisor IOS" you'll find information about the Native IOS (Native IOS = Supervisor IOS). Hybrid is where the switch side of the box runs a CatOS and the router part (the MSFC1/2) runs an IOS. Under Native (or Supervisor) IOS, the IOS controls the whole box. So basically with Native IOS, every switchport can act as a separate router interface, so it's like having a router with 200+ ethernet interfaces =).
I know that's not what you want to hear, but digging on Cisco's website is about the best way to figure out all of those details.
