Pros
Pro Generous free plan
The free plan allows you to log 10 million events per month. There are also 2 paid plans - Business and Enterprise. Business costs $995 and allows for up to 100M events per month while Enterprise has the price is negotiated on a case by case basis and supports an unlimited number of events.
Pro Event Flows visualize popular user paths
Event Flows, an Enterprise level feature, shows a branching user-action path from or towards a certain page/action.
For example, it could show most popular actions performed after landing on a product page or the most popular path towards clicking the buy button.
Compared to funnels, that allow you to track if users follows a predetermined path and where they drop off, Event Flows show what users choose to do instead. And while it's possible to create a funnel for each branching path, that involves a lot of time and some guesswork which is not present in Event Flows.
Additionally, it's possible to integrate Amplitude with Mode to create a User Paths report. It's similar to the Event Flow, but visualized differently.
Pro Gives you raw SQL access to your data
Enterprise customers can get direct access to Amazon Redshift's PostgreSQL Database. This offers multiple benefits - it allows for queries that are not supported by the dashboard, gives portability and ownership and allows using that data to build realt-time services based on that data.
