You shoudl really test drive both Honda and Toyota. They are both neat cars.
The conventional need for power is based on the direct relationship between engine speed and power output. The Honda still has that direct tie between the engine and wheels via the transmission. To move at a specific speed the engine needs to turn at a specific speed and needs a large enough engine to make sure that it's in teh powerband at that engine speed.
The Prius uses a continuously variable transmission (CVT) that provides roughly the same horsepower and torque no matter what speed the car is traveling. The engine speed is not coupled to the wheel speed, so that a weaker engine can move the car at speed efficiently.
The Accord will have a faster 0-60 time, but that measurement is not as useful as it used to be since the power curve for the hybrids can be radically different from a conventional setup. When comparing conventional designs, the 0-60 can be used to help guess at passing ability, hill climbing, etc. That does not appky when hybrids enter the mix.
In real life, a 70 HP engine pulls my 2,800 pound Prius up a 6 percent grade and will accelerate briskly as it does so. It uses the 44 HP electric to help accelerate but uses only the ICE to maintain that 65 MPH speed. I don't drive every car on the market, but I do rent them from time to time. I know the 2002 Prius climbs hills better than a Mustang with a 5.0, and that it is more comfortable and economical to boot. It's actually fun to merge onto a freeway in San Diego where it's nothing but hills.... but not in the Mustang.
Anyway; try all you can. They are all fun.
