MS SQL Server has always been good at managing itself. I can only guess it is getting better. But Oracle needs the finetuning, and I can't see that changing anytime soon, with Oracle some queries basically require that you use a IOT, other some are better with partitioned storage, and so on. So your premise is extremely dependent on what DB you use.
