What marketing automation software do you recommend to go along with Zoho used by my sales team?

 I am confused. There are so many: Marketo, Hubspot, Act-on and other marketing automation software available. I have read a lot about Sales and Marketing alignment. Which marketing automation solution will you suggest for my marketing team which can go well with Zoho CRM which is currently being used by my sales team.
