Tiers in The SEC

[Lucky SC]

I was reading through the thread on the Florida fraternities and it brought up the "tier system" which it seemed questionable if it was a legitimate thing or if it something made up by people. Then i started to think how does this whole tier thing branch out across schools that are pretty much the same... in this case, the SEC having brought up UF.

So if there is a tier system, then how do the fraternities match up at say Alabama, UGA, LSU, South Carolina, Tennessee, etc? is there some kind of trend we see here for particular fraternities in the area?

Have the same fraternities been strong since conception of the chapters or the regional area, leaving no room for competition (basically the rich get richer deal)... or does whos the "best" cycle from time period to time period.

I found this an interesting topic, and wanted to know yall's opinion on it because there seemed to be a lot of controversy in the other thread.
