In fact, Oracle also funds the open-source version, OpenJDK.
The Oracle EE JDK has some extra features which can be enabled (e.g. fancier G1 garbage collector, IIRC), and there's also GraalVM EE which provides an even faster runtime. Also worth noting GraalVM CE (Community Edition) which is pretty spectacular. Futamura Projection, anyone?

That said, OpenJDK works totally fine for many cases.
