Have had both. Love the CT. Prius was a turd. Its amazing how many things Toyota can do with plastic to make an interior ugly. CT is a completely different world for not that much more money. Admittedly I baby the CT but I am getting about 48mpg. The Prius was 52. Buy the CT. You will love it. And even if you don't there will be a long line of people trying to buy it from you.
