I think in the end, all of this engine matching paranoia will come to an end once electrics finally replace internal combustion's. But in the meantime, the CVT theoretically has the capability of making all shifting situations as smooth as possible using IC engines, almost as smooth as an electric. However, there are some real world problems with CVT's which I've heard of, such as requiring a really expensive oil change, after a specific amount of time. I don't own a CVT, so I'll let CVT owners explain it to you.
The engineer in me is really fascinated by the CVT, but the cheapskate in me would rather put up with a traditional automatic or a manual.
