I am looking for an email marketing tool. MailChimp vs Active Campaign?

MailChimp vs ActiveCampaign which one is better? I would like to send emails to my contacts that I will collect through opt-in forms in my WordPress site and then send those to one of the email marketing tools. I was wondering which one would be a better option in terms of pricing, features and reliability.

I have gone through the features of both and it seems like Mailchimp is more creative in terms of email designs and templates but it lacks the automation feature like ActiveCampaign. So, can anyone suggest me, which one would be a wise decision to choose and also if you can suggest any other email marketing or CRM tools than that would be helpful as well.

Thanks in advacned!
