CRM Recommendations

Can you help me find the best CRM to used in a growing business? I already tried using Convergehub and it was such a disappointment. It is a slow pace in updating, it provides data that has missing information in it which makes it unreliable. When it comes to the task manager, it does not even show if the task that has been assigned was taken care of or not which results in more workload. Implementing this software also cost a lot of money but it's not worth it. So I hope you guys can help find the best CRM to use. 

Sorry, but all I can do is what you can do on your own, use Bing and Google.
