I don't think the SEC is a choice, but if it were, I would still go with the B1G. The B1G's vision is national, and if you look at the tea leaves, their future plans look to dwarf the SEC's aspirations. The SEC wants to maintain a regional stranglehold on the South and Southwest. That's fine, but one day the SEC won't be the "SEC" any longer. All things are cyclical, and the SEC will eventually lose it's place on the pedastal of college football. The SEC also has tied themselves to ESPN...and if you're paying attention, ESPN's footing looks to be shifting. Disney is looking to offload parts of ESPN...which there's a REALLY high probability that ESPN will be dismantled pretty soon to investors. That means cost cutting, spinning off/selling of divisions, etc. Good luck to the SEC if that's the case. Overleveraging to obtain media assets is what got Diamond/Bally into trouble.
I read somewhere that the ACC contract is actually more profitable for ESPN than the SEC. The SEC brings in more revenue, but the profit margin is much smaller than the ACC. That's not a situation I want GT to be a part of.
Some of our older Yellow Jackets family may be nostalgic to return to the SEC, but that would be a BAD move. Not only in terms of $$$, or the scenario outlined above, but the SEC has shown they're OK with members cannibalizing each other. In the end, the SEC will turn out to be its own worst enemy. The B1G has high standards in the classroom and on the field, and IMO, that's is in line with why Dodd left the SEC in the first place.
I believe in time, if GT joins the B1G, GT will return to a "Southern powerhouse" like back in Dodd and Heisman's era. When B1G teams like Michigan, Ohio State, Penn State, USC, UCLA, etc. come to BDS, we will again play in front of a packed stadium. When, not if, we start winning against those teams, elite athletes will want to stay home to play for GT against those teams as well.
Thomas Wolf wrote "You Can't Go Home Again." The themes in that book ring true for GT...GT would be wise to leave the SEC in the past and move onto to bigger and better things.
