Trivial discussion: '67-'69 Barracuda: Fastback vs. Notchback- your opinion?

Yep. This thread will be full of pure opinions...but it has been on my mind for a while so I'd love to hear what you guys are thinking these days.

I think it's safe to say that the majority of us here are fans of the '67-'69 Barracuda in all three body styles. Recently, it seems that the notchback Barracudas from this generation have been gaining a bit more affection from the community. I wonder if the opinion might be evolving as cars are collected and continue to become rarer all the time and folks start to look at the "lower" models with fresh eyes.

So the fastback was higher trim level, correct? Unlike the competitor Mustang Coupes vs. Mustang fastbacks, where one body style is classic and beautiful (fastback) and one looks very down-market by comparison (coupe/notch)... the Barracuda manages to look comparably elegant and beautiful in both versions (in my opinion). Yes, one was considered to be a higher model but 50 years later, I personally find it hard to see it that way.

To those of you guys who were around back then, how were these models regarded back in their day?

How do the body styles compare for weight, balance, rigidity?
Are there significant differences in aerodynamic stability?
Are there differences that go beyond the sheet metal above the fenders/trunk?
Were some drivetrain combinations only available in the fastback but not in the notch?
Was it possible to load up a notchback with the same trim level as the fastback?

Any thoughts, opinions welcome.
