Salesforce Experience
Salesforce
Sets the standard for CRMs. Used by many, hated by some (sometimes me), loved by even more (also sometimes me and see: Dreamforce Dreamboat). Off-the-shelf Sales, Marketing, and Service Clouds (and many more) with built-in functionality beyond one's imagination. Plus incredibly robust point-and-click automation getting better with every release and the always available backend Apex and frontend Lightning coding options for expansion and customization.
