In my opinion, I like the 1 3/4 inch drop better. It gives it a little more of a sleek look when you look at it, but it doesnt drop it to the point that your scraping everything you drive over. I dropped my integra about 3 inches with coil's, and damn did it look good.
But it all comes down to your own opinion. You could try
www.cardomain.com and check out the civics there, usually they will say what drop they have.
