Honestly, this is a no brainier for someone looking at a compact CUV. The price difference is likely to be negligible compared to the fuel savings. The only downside to the Honda system is the setup vs Toyota. By using direct drive the engine uses a lockup clutch to connect to the wheels at speeds over 45 MPH, but it's a fixed ratio, so at higher speeds the mileage can start to drop off pretty fast. For instance at 60MPH I'm seeing over 50MPG, 65MPH I'm at 47MPG, 70MPH I'm at 45MPG, and 75MPH + it falls to 42ish or lower. The Toyota system is better at higher speeds, but the Honda feels like an EV at low speeds.
