The ease of use! Very customizable, many features for different business needs including reporting structure in place to keep track if things are working as intended or not (i'm looking at you Salesforce). Honestly it's hard sometimes figuring out how everything works - there is definitely room for improvement here but overall I like that they have kept up with all their updates since launch last year very well so far.-The ability/ability access from mobile-Reports generation & tracking customer leads / activities through website visits etc.
