Manual will have a faster 0-60 time b/c it will launch from start faster than the CVT. I have the CVT and Have been driving it at the local autocross events for 6 months now. I did not buy the CVT w/ the intention of autocrossing it. It just ended up that way. The car is doing very well in its class though. See the following results from april:

I took second in Novice (Damn R32 just has too much power, he would have won street tire class if he wasn't in novice). I would say if you care more for faster 0-60 time, buy a manual. If you buy the CVT and drive it in manual mode, and shift at the recommended speeds in the owners manual. As far as living in the city, that's why I bought the CVT. I really have no complaints about the CVT tranny since I've been driving it.
