Hello, Emerald Green.
I have not seen any reviews of the 1.0L CVT -- primarily because they're in Japanese!
The CVT will sap more power & acceleration than the manual. It will be considerably slower to be sure. Whether that's acceptable, only you can answer.
We have a handful of 1.0L owners in the forum (all manual shift), and only one of them occasionally complains that the engine isn't powerful enough -- though I expect that reflects more on driving style.
I'm not sure your motivation for wanting the CVT, but in the real world, manual transmission drivers are getting better fuel economy than CVT drivers, despite the government ratings predicting the opposite.
Anyway, welcome to the forum!
PS: you chose Curacao as your flag -- are you really there?
