The verdict
If you run inbound sales with several reps, form submissions that must be routed and a CRM that records ownership, I'd pick Chili Piper. SavvyCal can share meetings across a team, but it is not built around qualifying rules and CRM ownership.
If you book many meetings with prospects, candidates or clients you already know, and the first impression of your booking page matters, pick SavvyCal. The overlay lets the invitee find a time that works in one step.
For most small B2B teams, SavvyCal is the easier fit, because outbound and known contacts are more common than a flood of inbound demo requests. I'd only choose Chili Piper once inbound volume justifies the contract and the routing work.
