+1 vote for the 450h. I test drove one with 20" rims and was surprised how smooth and composed it was over Toronto roads. The V6 in it was excellent too, like it wasn't sporty but pulled hard with with satisfying sound note.
Another things I've discovered after almost a year of driving a hybrid car, is how convenient and smart its HVAC is. Since it's not engine driven, the AC works all the time regardless if the engine is running or not, making it very convenient and efficient when the car is parked and let's say you are waiting for someone in a parking lot. The cabin temp is consistently maintained while the engine comes on every once in awhile to top up the battery. Similar story with heating in winter.
Also, Toyota hybrids are easier in DIY maintenance, should you be so inclined.
