Anyone try Mailchimp integration with CRM? Is it better than Campaigns?

Has anyone here try Mailchimp integration with Zoho CRM? I am very unhappy with with Campaigns as well as the integration with Zoho CRM. I would like to do more lead scoring and consistent emails.

I love Mailchimp, but am unaware if plugins like Zapier make it work well with CRM.
