Best free CRM out there (in my opinion)

I use it for professional and personal purposes and it's a pleasure to work with it everyday! All of my contact information is collected in individual records in one central source. I can view contacts and deals. I can create tasks in a traditional table view, or by using the intuitive board view. I can drag deals from stage to stage as they progress through my pipeline. It works seamlessly with HubSpot Sales so I can check all things related to partners and prospects in one place.
