I know the answer to this is out there. I just can't figure out how to phrase it into my search. I've been trying to figure out the hierarchy of the various main manufacturers tiers. I was able to find a modern match up but nothing older. This is what I've pieced together, though I imagine it's wrong and/or I'm putting together things that weren't manufactured at the same times.

From top to bottom tier:

Campagnolo:

Super Record
Neuvo Record
Record
Chorus
Victory?
Trophie?
Athena
Centaur

Shimano:

Dura-Ace
Ultegra (new name for 600?)
600
105
RX-100
RSX

Suntour:

Superbe
GPX
VGT
FT

Sorry I know so very little about Suntour. I bet maybe only one of those is actually a groupset

Anyway. Sorry for asking such a basic question. I'm sure I'm all wrong etc. I know in time it'd piece itself together but I suppose I'm impatient. Also, I have read more than once that the older Suntour groupsets were the best of the three, but inability to upgrade is what caused the fall of Suntour. Any real group opinions as to the equality of these three? Also, I know there are others like Huret and Stronglight but I'm already way in over my head!

Thanks for putting up with the newb.
