I booked my car recently, had the same decision problem so visited all the show rooms I could before deciding where to book. You are right on Defense and Sharah-e-Faisal, heard alot of stories, and the people at Honda Defense didnt seem very friendly when visited and still had some resentment with Honda Sharah-e-Faisal regarding some jugaar denting repair work with my previous civic. Already had a terrible experience with Honda Quaideen as it took them 6-7 months to give delivery for our City (this was back when the duck shape was launched so long time ago), we were so fed up with them that sold it for On and got a used civic from the market instead. That left only Honda South and Honda Drive-In, decided to book at Honda South as that was nearer to me. Honda South clientele is usually corporate, so hope I have a good experience this time. They did give me my customer reference number in just one day. Lets see how it turns out. Fingers crossed.
If you are booking the plain I-Vtec version and want quicker delivery, would recommend checking with Honda Sharah-e-Faisal, the sales guy there promised delivery within a week for plain version, rest of them said one month. For Turbo and Oriel all gave same delivery timeline (3 months and 4 months).
