Which Template site gets better results? Z57, Agent Image or Point2

I have worked on all of the mentioned tempate sites, but haven't seen any long term results, so I thought I would throw it out to the experts.

Times are tough, and I want to be able to effectively counsel a client on which site to purchase for the best lead generation. Do you think that the Point2 Professional gets the same lead results as the Z57 site with comparable monthly payments...or is it worth investing in a "semi custom" agent image site. Granted, it all depends on what content is added, keywords, metatags, etc...and I know tto be skeptical of anyone offering a great deal to get you great rankings.... But as a general question, could I get some general answers?

Thank you in advance for your help.
