With a cvt its nice as you have an infinite range of gearing so you will not be in a situation where one is too low, the other is too high. You can also hold the engine at a sweet spot or rpm and watch the expression of your passengers as you speed up, but it never "shifts".
Having grown up playing with tractors Im use to locking in rpms.
Now, what no one has said is that cvts generate a lot of heat and when they start to warm up they become gutless. After several 0-60 runs in sport mode my cvt fails to act like a 7 speed automatic. It just reverts back to the cvt behavior til it cools off. There are some test drives of Nissans off road vehicles where it starts to get sloppy in operation as the going gets tough.
Me, Id rather have a car with gears and electric activated clutches.
