It depends,

How many mailboxes in all?
Do you want to manage the users department wise or don't care?
Splitting database gives administrator more control and in the event of database outage entire company is not impacted.
Is HA a requiremend... DAG?

Also i highly recommend to use the Storage calculator which will tell you depending on the input how many database to split the environment into along with the number of users.
