Here's my call...not that it matters.
I had a 57 Oval, 69 and 73 Super.
The 69 was my favorite by far.
The Super front end is smoother but a bitch to work on. Mine ALWAYS had a shimmy somewhere between a couple different speeds. I verified this over and over as I drove my friends' super beetles too. In Tampa/ ST Pete there was a huge group of us that would meet up. I also took regular weekend trips to and with the Fisher Buggies crew too. The 68-70 models were rock solid, had the look of the classic beetle with a little umph and you could pop of the plasti-dash and go back down to bare metal vintage. (Man I fuckin hate those squared off plastic dashes on the supers.) The really early models (pre-63ish) are becoming very rare now. In fact I think you should skip both cars and wait for an earlier model.
If all you can find are late models go after something more fun like an early model Honda CVCC or Datsun B210. These will break down almost as much. :) Oh also all beetles rust. Watch the bottoms of the doors and rear side air intakes on late models. These can set you way back on a repaint and will require replacement of the sheet metal or door (skins).
