IDXSEOPRO

I looked all over the web for real estate software and the ones everyone talks about is Open Realty and EZ Realty.

I'm registered at Open Realty now and I'm a member of the EZ Realty site as well and I'm asking the same question there?

Which is better for;

Search Engine Optimization
Ease of Use
Functionality
Features
Integration with CMS's
IDX integration
Speed of the application
Overall Support.
Also, which one is easier to design for.

thank you
