There was a time when a fresh install of Windows required over a day to bring up to current, if you didn't have install media with the latest service pack already applied. MacOS updates are fairly slow, though, so I don't know if it's a clear win. But I also don't think anything has gotten significantly worse in recent years; there have always been good parts & bad parts.
