Which would you rather have?

I'm considering a deal on a 70' dart gt right now. (I know, I know.. dart gt, didn't make em in 70.. well they did.. search google for more info on what the car is/was.)
Anyway: The real question is this: which would you rather have?
'70 dart gt, beautiful interior, decent exterior. 340, 4 spd, 3.91 rear, drums all around
or
'69 barracuda. interior rough. exterior better than the dart, but not perfect. 318, 4 spd, 3.23 rear, front discs
The dart is nasty. It violently throws you back in your seat. The cuda.. well, it's a 318. It's kinda quick, but nothing 'violent' at all. Both cars are bolted up equally (4bbl carbs, mild cams, dual exhaust, headers, 340 has an eddy intake man, the 318 has a stock 340 intake man), so they are both bolted up pretty well, but if heads were added, they would make a better difference on the 340 by far IMO.
It is to be a daily driver, I travel back and forth to school every weekend on the highway for 30-45 mins, the rear can be swapped out of either car, and I also want it to be fast. The 318 doesn't seem to cut it for the fast part. The 340 is plenty quick for me.
So, opinions?
