To each his own, if the i-shift suits you and you don't like the CVT so be it.
I think Vic hit the nail on the head here, the CVT and i-Shift are like chalk and cheese. Both require subtle modifications to your driving style, if you are used to a manual... it's just that the CVT and i-Shift behave very differently in some circumstances.
Personally, I don't mind automated manuals, though they not without problems. The actuators on most manufacturer's gearboxes seem to be particularly failure prone, and unless the garage understand how to carry out the necessary calibration procedures, even a clutch change can cause untold grief.
I often wonder why Honda never offered a Jazz with a conventional auto in the UK, when they are so common in other markets. A bit off topic, but if you are into autos and ever get a chance, try the CR-V with the fabulous ZF 9 speed auto - it's as smooth as silk.
