well, personal opinion, if I could afford both, i would go for the Accord.
Different car type, sizes, quality, comfort.
For me my car has to full-fill my needs. Go to work, travel with 2 people in the car when needed, space for luggage, easy to drive and have some "fun" with it sometimes, etc. Since this, my Civic is excellent. I don't need extra space, don't have the need for a bigger car (and it's running costs, insurance, the car itself costs more than a Civic). It's all about your need I think, but of course, this is the way I think.
For example, I was thinking to buy a Type-R or the 1.8 petrol in the beginning (didn't want a Diesel because of the big price difference here in Portugal, and I preffer the petrol to diesel
) , but, after some rational thinking, I make to much mileage, drive long every day. With this the 1.8 is more fuel efficient, less hard-core suspension to drive all days, and the maintenance is cheaper as the car itself. So I went to the 1.8.
just my 2 cents
