Depends on your needs. The Accord is larger and (especially in the 6-cylinder) more powerful. The civic has a lower sticker price and better gas mileage (by virtue of being smaller).They are both very reliable.The 2/4-door question again depends on your needs and typical usage. If you have or soon plan to have kids, absolutely get the 4-door. From experience I can tell you you do not want to be wrestling a car seat into the back of a 2-door civic.
