Both can slow down the experience.
The alternate cron will issue a redirect which creates more work for the
customizer, but not exit immediately, which means shutdown will be delayed
(see future changeset from koopersmith in #20507 where we check for a token
printed on shutdown to ensure the response came from the customizer).
The update checks could also cause bad data to be sent. In particular, the
currently active theme would be incorrect.
see #20507.

If the custom background default wp-head-callback (_custom_background_cb) is used, we use postMessage for all custom background properties. Otherwise, we use full refreshes.
When using postMessage, the preview recalculates the custom background CSS block, allowing it to omit CSS values when they are not present and fall back on the original CSS.
