Personally I use Realtynaís Wordpress CRM. It really depends on what youíre looking for.
This CRM is a good experience, as you are able to manage your customerís every need in one place. Also, the system is user-friendly as lead-generation and follow-up processes are automated.
The opportunity to have unlimited users and records is also a great plus of this product.
In this CRM there is included the following:
You can capture a lead through different forms in the website. You can also gather information from the leads and monitor their activity through:
Login history
List of visited properties
List of saved searches etc
On the other hand, you can also provide necessary controls over the privacy of information within the system between all users.

There is also one more thing which I find very useful: you can sync your Realtyna CRM contacts with ZOHO CRM. Doing this, you can have more advanced features, which include:
Multichannel support
Trend analysis
Sales performance metrics
Third party-app integration support etc.
