I actually own the Hybrid and I've been getting pretty good gas mileage 40+. I was in DC last weekend and got 43+. I really think it depends on how you drive, eg. slow down early, accelerate slow, use cruise control, and always drive using ECON. The power is not too bad for a hybrid. Turn off econ and it basically drives with the power similar to that of a civic.
I bought the hybrid because I wanted all the features and comfort, plus great MPG. So it was basically this or the CT200h (only buy Japanese because I trust the quality). The ILX came out a couple thousand dollars cheaper and to be honest, it looks a lot better externally and internally. The only thing I wish it had was side dimming mirrors and lumbar support in the main seat.
Just FYI, I used to own a Honda Accord 2008 Coupe v6 which has around 270+ HP... so that was a big change. But I was only get 22 MPG with that. I don't really need the power any more anyway since i'm driving just to work and on vacation.
