The good thing is you should be able to test drive a Civic and a Prius (or Camery).
I'd still query hybrid forums because one test drive is just a sampler - it took me weeks to "know" my Honda Insight. Actually months, but it's fun.
I'd characterise Toyota as emphasizing the hybrid system, while Honda emphasizes efficient gasoline engines. Both are important parts of great fuel economy, but it's why Toyota hybrids do better in stop-and-go traffic, while Hondas cruise on less gas.
msantos has a Prius and a Civic - if he does not respond, consider PMing him. He is happy with both.
