What is the difference? I have the tutorial through and was already outside the tutorial world.
Contentwise, the Bedrock and the Java Edition hardly differ. It may be that one gets an update earlier, but nothing more.
The really relevant difference is that the Java Edition is programmed in Java. But she is modding-friendly and has a huge community, countless servers and game modes.
This is the Bedrock version, which is compatible on the consoles and from the Windows 10 Store, just cross-platform cross-platform games, except with the PS4 version.
You should buy the Java Edition if you do not need Crossplay with console players.
