For which is better, i don't know. Ultimate MPG is usually achieved in a manual, and some hypermiling techniques are much easier to do in a manual. Drivers can abuse the IMA battery much easier in a manual, also. The CVT appears to be quite demanding of its regular 25-30K or so fluid changes. Otherwise, transmission issues ensue.

On the 2006-up HCH2, you have no choice, CVT only.
I think Honda decided it's easier (and maybe better) for them to manage the IMA battery and its state of charge using the CVT, rather than the 5-speed.

I'm very happy with my CVT, and plan on being diligent about the fluid changes.
