I prefer Trulia over Zillow since Trulia allows you to post blogs where Zillow does not. I also feel that Trulia has a more user-friendly appearance. I think using any avenue to give yourself and your listings more exposure on the internet is worth trying if it is not too costly.

If trulia had the nice website...... good bye Zillow. I havent tried Realtor.com(r) yet.
Very good question, I was wondering how other felt.
