I'm pretty lucky, I've just now been able to drive both for quite a few miles. My car is in for a remote starter to be installed, and I got a loaner 2012 WITHOUT MT.
I can see how some would not like it. When moving from a stop you can feel the clutch engaging and I could feel a shudder. I also noticed the issue of going around turns and it acting weird. I also know that if you are to do as some stated above, and THINK about the foot input, and how you want it to shift, and where, the transmission will react the way you want it to.
I really like the 6th gear, and how it drops the RPM's.
Overall I am impressed actually by it, and think after driving it some more, I could get used to it, although the car is getting 10mpg less than my 5 speed, and that doesn't bode well with my commute.
