Trulia vs Zillow What has worked better for you?

I read the Active Rain article on how has Facebook worked for you? and started thinking about other lead marketing I use. Facebook has been good for me because I get calls and emails from friends and acquaintance's for information on rentals and sales. Most of the time it is in reference of they did not know I did real estate or was glad I still was in business in this economy. The general census I get from outside people is they think all Realtors are broke and not working. Facebook helps me show that I am an Active Realtor and still doing fine.

My Main question is I use Trulia for about 2 months. I bought part of my zip code for leads and had about 3 emails and one turned into a lead for a buy. Seems pretty good in my mind but wanted to see if other people had better success or ideas using Trulia or better success with other websites?

Thanks and Best wishes to all Realtors making it happen in this market!
