100% this. I book a decent amount of my leisure flights on Sapphire points only. Rebooking is trivial if you book directly with an airline, you can often do it within the app for that airline itself. Rebooking with Chase is often a 30-60 minute ordeal that can only be done over the phone involving 2-3 transfers. Often this is not even something that is your fault - the airline can rug pull the flight by changing the time or cancelling it, forcing you to undergo this ritual.
