Most all the hybrids are CVT's, manuals just don't lend themselves to such. It's sort of a defining difference and a cultural touchstone, there may be some PDK type auto's out there which are
better (in every way technically), but still aren't as traditionally engaging as a regular manual trans.
6spd jetta tdi has options, performance enhancement. I'm assuming anyway, every other TDI does. Camry hybrid? I'm sure it's a very, very good car, and I mean that, but there are a significant number of people that want something more involved and interesting in an automobile. It usually begins with a manual transmission and a fat torque curve.
And if one does not want those things, that's perfectly fine. Both sides, and the inbetween's, need to realize that it's OK to be other than how they are. That's why there are lots of cars for sales every year instead of like, two..
You can buy a couple year old Porsche for less than the Jetta or Camry, and clearly it's a better car since it's a Porsche, right? But you don't, generally. Maybe the Porsche is a little tooo involved and interesting. Different strokes and all that.
