In one line

Kafka brokers by the hour plus storage. Serverless swaps that for cluster-hours and partition-hours.

What gets missed

Neither mode charges per message or per API call. Serverless bills every partition every hour, so an over-partitioned idle topic costs real money, and Express brokers add a per-GB-written fee.
