Which is the most recommended Wordpress Pugin for Lead capture?

Hello,

Our company have many WordPress based sites, and planning to capture Leads from these sites automatically to the Sugar CRM Leads module.

Browsing the https://wordpress.org/plugins  section I found 3-4 plugin, but theye are not to convincing, and all needs at setup an SugarCRM accoutn with administrator rights. Im nost sure about the safety of the method. I rather be used an Account with restricted access only for the Leads module.
