Personally I like the Honda
Personally I like the Honda Clarity better, but part of that is that I've owned so many Hondas. Ironically, I don't have any Hondas now, and still own a Toyota Corolla as a backup car. The Prius Prime seems to match the Clarity's sales, then periodically surges way ahead, then drops to equal, and then surges ahead again. It remains the top selling PHEV in the U.S. I do however wonder if the new Toyota Corolla hybrid is affecting regular Prius sales.
