The Toyota is nothing short of amazing. The HSD is going to be hard to beat for the 80% of drivers that prefer an automatic or CVT style transmission.

Honda's technology is better suited for a manual transmission. In fact a manual is impossible with HSD as the heart of HSD is the split power device which is a CVT.

Because of advanced features like pumping the hot coolent into an insulated container and the Atkinson cycle engine IMO Toyota is ahead. However Honda could improve their hybrids to include such features and still be using IMA technology.

IMO IMA is no better or worse than HSD but also IMO Toyota is a little ahead (currently) with the Prius. Still personally I prefer a manual so that rules the Toyota and HSD out for me.
