Which should you choose?
Zendesk is the lighter-weight option (Paid), while Sierra sits higher on the pricing ladder (Enterprise). Sierra is built around enterprise customer experience organizations; Zendesk leans more toward growing smbs. Shortlist the one whose strengths line up with your biggest constraint.
