When Sierra is still the better choice

Switching tools costs time, so only move for a clear gain. Sierra is still the better choice if you are a large brand that wants a custom, services-backed AI program. It also makes sense to stay while you are under a contract you cannot leave yet.

If you are unsure, run Convocore next to Sierra on one channel first, for example website chat or after-hours calls, and compare the answers and the cost for two weeks before you move more traffic.
