In my opinion, java is more versatile. While bedrock is Microsoft's main focus because it brings together all communities and makes them money off of marketplace, the java community runs itself, with mods, shaders, plugins, etc all releasing from the players. Plus, java can do way more then bedrock anyways, so if you're looking for things to do, and want to customize the game (and play on a computer that wasn't made 14 years ago), then play java.
